Extrusion blow moulding of Braskem HDPE HS5407 into tight-head 5 L and 20 L jerricans for organophosphate, pyrethroid and emulsifiable-concentrate agricultural formulations places simultaneous demands on parison melt strength, pinch-weld coherence and environmental stress crack resistance. In single-station and dual-station accumulator-head machines with screw diameters from 60 mm to 90 mm and L/D ratios between 24:1 and 30:1, the grade is processed with barrel temperatures profiled from 160 °C at the feed throat to 200–210 °C at the die head. Melt temperature is kept below 220 °C to limit oxidative chain scission; local residence times above 6 min in the accumulator produce gel specks that nucleate stress cracks at the bottom pinch-off. A parison programmer with 15 to 30 points is used to hold sidewall thickness above 1.2 mm and base chime thickness above 2.0 mm, while tail flash at the mould parting line is compressed to 0.3–0.8 mm by tuning clamp force and pinch insert geometry. Cooling water in the mould jackets is maintained at 10–18 °C, and blow pressure is set at 0.7–0.9 MPa to force the parison into handle root details before freeze-off.
Formulation adjustments for agricultural packaging include a pumpable carbon black masterbatch at 2–3 wt% for ultraviolet exposure during open-field storage. The masterbatch carrier should be a high-molecular-weight HDPE or linear low-density PE with a melt flow index below 1.0 g/10 min to avoid local viscosity dilution at the die bushing. Titanium dioxide white masterbatch at 4–6 wt% is used only when peroxide-containing formulants are absent, because residual transition-metal compounds in some pigment grades catalyse oxidative attack in contact with oxidising tank mixes. Regrind from tail flash and rejected tops may be reworked at 20–30 wt%, provided the fraction passing a 0.5 mm screen is excluded and moisture is held below 0.03 wt%. The terminal articles are tight-head 20 L jerricans with 42 mm or 51 mm UN neck finishes, induction-sealed PE/aluminium foil liners and eared closures. Drop testing is performed after conditioning at -18 °C for 24 h using a rigid concrete target; the acceptance criterion is no leak and no visible crack at the handle pinch or base flash.
Compliance for the filled pack is anchored to the UN Model Regulations Chapter 6.1 and ADR 6.1.3 when solvent-based formulations are assigned to Class 3 or Class 6.1. Environmental stress crack resistance is verified on compression-moulded plaques under ASTM D1693-15 Condition B with 10 vol% Igepal CO-630 at 50 °C; for jerricans exposed to xylene and cyclohexanone-based formulations, slow crack growth is further screened using ISO 16770:2004 full-notch creep test at 5 MPa.
| Test method | Condition | Failure mode controlled |
|---|---|---|
| ASTM D1693-15 Condition B | 10 vol% Igepal CO-630, 50 °C | Environmental stress cracking in jerrican sidewalls |
| ASTM D2463-15 | -18 °C drop impact | Pinch weld and handle weld brittleness |
| UN Model Regulations 6.1.5.3 | Hydraulic 100 kPa for 30 min | Leakage through tight-head closure and seams |
| ISO 16770:2004 | FNCT, 5 MPa, 50 °C | Slow crack growth in aggressive solvent formulations |
| ASTM D3895 | OIT at 200 °C | Antioxidant retention after regrind recycle |
The grade is not assumed to have food-contact status unless the current FDA 21 CFR 177.1520 letter or Regulation (EU) No 10/2011 compliance statement is confirmed by Braskem for the specific formulated compound.
High-viscosity engine oil, white spirit and low-aromatic hydrocarbon solvents packaged in 1 L to 5 L extrusion blow-moulded bottles attack the base pinch and handle weld not through dissolution but through stress cracking at the frozen-in parting line. On shuttle machines with screw diameters from 40 mm to 70 mm, HS5407 is run with barrel temperatures from 165 °C to 200 °C and a die-head temperature of 190–205 °C. The melt is not pre-dried unless surface condensation exceeds 0.05 wt%; a nitrogen-purged hopper is preferred when ambient RH exceeds 60%. Blow air at 0.6–0.9 MPa inflates the parison in less than 1.5 s, and the mould is vented along the parting line to prevent air entrapment at the handle root. Pinch inserts are set to compress the tail flash to 0.4–0.8 mm; flash thicker than 1.0 mm creates a weld notch that lowers drop impact at -18 °C.
Formulation at the press includes 3–5 wt% of an LDPE carrier masterbatch for surface slip and 1–2 wt% antistatic masterbatch when packaging non-conductive solvents, but antistat levels above 2 wt% reduce environmental stress crack resistance by plasticising the amorphous tie-chains in the HDPE matrix. Finished sidewalls are tested under ASTM D1693-15 Condition A in 100% Igepal CO-630 at 50 °C; a brittle failure before 150 h is cause for rejection. Drop impact is measured per ASTM D2463-15 at 0.8 m and 1.2 m after -18 °C conditioning. Terminal 5 L jerricans are qualified as UN 3H1 for lubricating oils up to SAE 20W-50, filled at 20–45 °C, and stacked eight units high for 28 days at 40 °C under a top load equivalent to 1.5 times the gross mass of the stack.
Automotive fuel shells blow-moulded from high-molecular-weight HDPE are selected for low-temperature toughness and stress crack resistance under fuel swelling, not for monolayer hydrocarbon permeation. In coextrusion blow-moulding lines with 2 to 6 extruders, HS5407 forms the outer and inner cap layers at 70–80 wt% of wall mass; ethylene-vinyl alcohol copolymer is placed at 2–3 wt% between maleic anhydride-grafted polyethylene tie layers; carbon black masterbatch at 2–3 wt% provides ultraviolet resistance. Die-head temperature is controlled at 190–215 °C, and the EVOH stream must remain below 225 °C to suppress gel formation. Accumulator-head shot size ranges from 8 kg to 30 kg for tanks between 30 L and 90 L. Programmed die-gap profiles maintain sidewall thickness ≥3.0 mm and pinch-flange thickness ≥5.0 mm; mould cooling water is held at 8–15 °C. Fluorination or sulfonation is applied after moulding when monolayer shells must pass given permeation limits; finished fuel tanks are validated by gravimetric SHED procedures under 40 CFR Part 86 evaporative emission protocols and by fire-risk testing under ECE R34.
Oxidative induction time is monitored by differential scanning calorimetry under ASTM D3895 at 200 °C; values below 15 min on the inner HDPE layer indicate antioxidant loss after regrind recycle. Impact is evaluated at -40 °C after immersion in CE10 and CE85 reference fuels; tensile properties are tracked by ISO 527-2:2012 on specimens cut from sidewalls. HS5407 regrind from flash may be re-used at 20–30 wt% in the outer layer only, not in the fuel-contact inner layer, to retain permeation margin. Terminal articles are 30–90 L diesel and gasoline tanks for off-road equipment, marine engines and heavy-duty vehicles; published data for specific tank configurations is limited, so each moulded shell must be validated against current OEM permeation and impact targets.
Because sodium hypochlorite, hydrogen peroxide and alkaline drain cleaners attack HDPE through oxidative chain scission and environmental stress cracking, bottles intended for these formulations require a restricted additive envelope and a narrow processing corridor. HS5407 is converted on continuous shuttle extrusion blow-moulding machines with screw diameters from 50 mm to 80 mm and grooved feed sections. Melt temperatures are held at 180–205 °C to limit carbonyl formation during plastication; carbonised melt left in the accumulator for more than 4 min is purged before start-up. The formulation excludes calcium and zinc stearate lubricants because metal carboxylates can accelerate bleach decomposition at the interface. A synthetic paraffin wax at 0.1–0.3 wt% is used for mould release, and a white masterbatch at 3–5 wt% is specified only when copper, manganese and iron residues are below 1 mg/kg in the pigment. Blow pins are chrome-plated and polished below Ra 0.4 µm to remove microcracks at neck and shoulder radii. Sidewall thickness is set at 0.8–1.5 mm with a minimum 0.4 mm in the handle web.
Finished 1 gal and 5 L bottles for sodium hypochlorite solutions up to 15% available chlorine are classified as UN Class 8 corrosive packaging group II. Drop tests at 0.8 m and 1.2 m after -18 °C conditioning are run under ASTM D2463-15; storage compatibility is confirmed for 6 months at 40 °C in contact with 10% sodium hydroxide and 12% sodium hypochlorite.
Large-format blow moulding of 125 L to 220 L liners and open-top drums is the most demanding accumulator-head route for HS5407 because parison hang time routinely exceeds 15 s, shot weight varies from 10 kg to 30 kg, and wall-thickness control determines both top load and drop survival. The grade is run with extruder melt temperatures of 190–215 °C and accumulator capacity at least 1.5 times the shot weight to prevent hold-up degradation. Parison thickness is programmed with 20 to 40 points; the bottom pinch-off is thickened to 6–10 mm because hydrostatic pressure at the base of a filled 200 L drum reaches 20–27 kPa and top-load creep at 40 °C controls warehouse stack height. Moulds are built with beryllium-copper pinch inserts and water jackets delivering 10 °C coolant. The formulation includes carbon black masterbatch at 2–3 wt% for ultraviolet resistance and a fluoropolymer process aid at 0.02–0.05 wt% to reduce die deposit formation during 72 h continuous runs. Compliance is anchored to UN 31H1 composite IBC receptacle tests and UN 1H2 open-top drum certifications; hydrostatic pressure of 30 kPa for 10 min and stack testing at 1.5 times gross mass for 28 days at 40 °C are applied. Terminal products are used for water-treatment coagulants, mineral acid dosing and liquid fertiliser concentrates where metal containers are incompatible.
Process conflict arises at the pinch-off insert: a sharper insert reduces flash but lowers weld strength; a wider insert retains impact but increases trim scrap. For HS5407, the working compromise is a pinch width of 3–6 mm with a land angle of 30–45°. When open-top drums are trimmed in-line, pneumatic deflashing must be adjusted so that cutter speed does not exceed 300 mm/s through the flash zone, otherwise micro-cracks propagate into the rounded base. The regrind stream is limited to 30 wt% because high surface area from ground flash accelerates oxidation during melt processing.
For non-potable chemical dosing tanks exposed to direct sunlight and diurnal thermal cycling, HS5407 is specified primarily for melt strength and resistance to slow crack growth rather than for short-term stiffness. Tanks from 50 L to 500 L are blow moulded with wall thickness from 3 mm to 10 mm; dry-blend carbon black masterbatch at 2–4 wt% provides UV stabilization and is dispersed through a static mixer in the accumulator head. Compliance under REACH 1907/2006 and RoHS Directive 2011/65/EU is maintained for industrial use; terminal products include agricultural sprayer tanks, marine waste tanks and water treatment dosing vessels.
Blow-moulded windshield washer reservoirs and coolant surge tanks are produced from HS5407 at 0.8–1.2 mm nominal wall thickness, with 2 wt% carbon black masterbatch for under-hood UV resistance. Melt temperature is held at 190–205 °C in shuttle machines, and the terminal parts are cold-impact tested at -35 °C per ISO 179-1:2023; continuous service is limited to 80 °C.

Braskem HDPE HS5407 is a high-density polyethylene homopolymer injection-moulding grade supplied as a free-flowing pellet resin. The product is identified by a melt flow rate of 7.5 g/10 min determined at 190 °C under a 2.16 kg load in accordance with ASTM D1238 and ISO 1133-1:2022, and a density of 0.954 g/cm³ under ASTM D792 or ISO 1183-1:2019. The grade is positioned for injection moulding of thin-wall rigid articles, caps and closures, housewares, toys, and small industrial components in which stiffness, dimensional stability, and moderate melt fluidity are required. Compared with fractional-melt blow-moulding resins, the higher melt flow rate shortens filling time and reduces pressure drop in cold-runner multi-cavity tools. Compared with high-flow HDPE grades, HS5407 retains a higher molecular weight fraction that supports greater resistance to stress cracking in thicker sections.
The crystalline fraction associated with the 0.954 g/cm³ density produces a peak melting temperature typically observed between 129 °C and 133 °C by differential scanning calorimetry. Vicat softening temperature is reported near 126 °C under ASTM D1525 or ISO 306. These values are not to be used as sustained service temperatures under load; they define the thermal-softening range at which dimensional stability and modulus decline. The grade is not hygroscopic. Pre-drying is unnecessary when the material is stored in intact, sealed packaging at relative humidity below 60% RH. If surface condensation appears after storage in an unheated warehouse, 2 h at 80 °C in a desiccant dryer removes surface moisture prior to processing.
At shear rates representative of injection moulding, between 1000 s⁻¹ and 10,000 s⁻¹, the melt exhibits strong shear thinning. Standard melt flow rate data do not provide sufficient information for gate and runner design; capillary rheometry at 190 °C, 210 °C, and 230 °C is required for accurate filling simulation. Pressure-volume-temperature behaviour should also be measured because the crystalline phase produces a discontinuous density change during cooling. Mould shrinkage for HDPE HS5407 is typically in the range of 1.5% to 2.5%, depending on part thickness, gate location, and holding pressure. Ribs and bosses require local thickness reduction or tool temperature adjustment to avoid sink marks because shrinkage is volumetric and delayed by crystallisation.
The melt flow rate of 7.5 g/10 min is measured under a low shear condition and is used as a lot-to-lot consistency parameter rather than a design value. The molecular weight distribution is sufficiently narrow to provide reproducible filling in multi-cavity tools, but it also means that shear-induced temperature rise is lower than in broader-molecular-weight extrusion grades. The density of 0.954 g/cm³ places the material in the high-density ethylene homopolymer range, which contributes to a flexural modulus near 1100 MPa and a tensile yield stress near 25 MPa. These properties are obtained from standard test specimens and should be adjusted for moulded-in orientation, weld-line location, and part thickness.
Injection moulding machines with general-purpose polyolefin screws having an L/D ratio from 20:1 to 25:1 and compression ratios between 2.5:1 and 3.5:1 are suitable. A free-flow non-return valve is preferred because the medium viscosity can generate a pressure drop across restrictive check rings. Barrel profiles from rear to nozzle are normally set between 180 °C and 230 °C, with the nozzle maintained near 220 °C. Mould temperatures of 20 °C to 40 °C are acceptable for thin-wall parts; increasing mould temperature to 60 °C reduces frozen-layer thickness and may improve weld-line strength at the cost of longer cooling time. In high-cavity cap moulds, cycle time may be governed by screw recovery because the shot weight is small and the cooling time short. A screw with a compression length of at least 8 D and a uniform feed zone avoids melt-temperature variation during recovery.
Multi-cavity tools require runner balancing because viscosity variation between lots is small but not zero. A geometrically balanced runner is preferred. In cold-runner systems, runner diameter below 4.0 mm may freeze before packing is complete, producing sink marks in parts. For caps, sprue diameters of 5.0 mm to 8.0 mm and gate land lengths below 1.0 mm are common. Tunnel gates in housewares should have a land length between 0.5 mm and 1.0 mm and an included angle of 30° to ensure clean break. Edge gates are used for larger articles where flow direction must be controlled to minimise warpage.
Because the grade is a homopolymer, it is unsuitable for continuous exposure to hot oxidising agents, chlorinated disinfectants, or aromatic hydrocarbons under mechanical stress. Environmental stress cracking resistance is lower than that of bimodal high-density grades designed for detergent bottles and industrial chemical cargo. Sharp corners, weld lines, and thick sections under hoop stress are initiation sites for stress cracking. Qualification for such service should include testing under ASTM D1693 or ISO 22088-3 with the intended chemical at the maximum use temperature. The material is not recommended for load-bearing service above 80 °C.
In thin-wall packaging with wall thickness below 1.0 mm, filling time is short, but the screw must recover the next shot during the cooling phase. HS5407 has a melt flow rate that reduces metering-zone pressure, yet the feed-zone bulk density and pellet shape control solids conveying. Undersized screws with L/D ratios below 18:1 may force a longer cycle than the cooling time would permit. Processors should evaluate recovery time against cooling time using shot weight, screw diameter, and backpressure not exceeding 1.0 MPa. Backpressure above this level can increase melt temperature and reduce viscosity, but it also increases screw recovery torque and may create gel-like degraded material if residence time exceeds 10 min at temperatures above 230 °C. Purging with a polyethylene purge resin is recommended when switching from coloured or filled grades to avoid black specks in transparent or light-coloured parts.
Hot-runner systems are generally compatible with HS5407, but the melt should not remain stagnant in externally heated manifolds at temperatures above 240 °C. Degradation generates a progressive reduction in melt strength and an increase in low-molecular-weight fraction, which can alter odour and migration behaviour. In valve-gated tools, gate vestige dimensions should be checked because the medium viscosity can produce stringing if the valve is worn. Shot-weight variation in production runs is normally below 0.5% when the non-return valve is maintained; a larger variation indicates ring wear or feed-bridge blockage.
Cooling time is dominated by part thickness. For an unfilled semicrystalline polymer with a thermal diffusivity near 0.1 mm²/s, cooling time estimated by the ejection-temperature method increases with the square of wall thickness. Reducing wall thickness from 2.0 mm to 1.5 mm decreases cooling time by approximately 44%. This relationship makes HS5407 suitable for thin-wall parts where fast crystallisation permits early ejection. Ejection temperature should be below the Vicat temperature to avoid deformation under ejector pressure.
The homopolymer structure provides good stiffness but limited environmental stress crack resistance relative to higher-molecular-weight, comonomer-modified grades. In aggressive wetting agents such as nonylphenol ethoxylates, stress cracking can occur at low strain levels. Parts that are press-fit, snap-assembled, or exposed to detergents should be tested under ASTM D1693 condition B or ISO 22088-3. The resistance of HS5407 to aliphatic hydrocarbons is acceptable for short-term contact, but aromatic hydrocarbons, chlorinated solvents, and strong oxidising acids cause softening or oxidative chain scission. Contact with PVC gaskets or plasticised polymers can produce plasticiser migration that reduces surface hardness; design compatibility testing is required.
Ultraviolet stabilisation is not incorporated in the standard HS5407 grade. Outdoor service requires addition of a compatible hindered-amine light stabiliser or carbon black masterbatch at the converter level, and the final compound must be re-evaluated for mechanical and regulatory properties. The base polymer does not contain flame retardants, antistatic agents, or slip additives; additive packages are the responsibility of the converter and must be dispersed under high-shear conditions to avoid surface bloom. Antistatic agents and slip additives can migrate to the surface and alter coefficient of friction and print adhesion. In caps, antistatic agents may interfere with induction sealing; compatibility of the additive masterbatch with HDPE should be confirmed by measurement of seal strength after 24 h. Pigmented grades can show slight differences in shrinkage and cycle time because pigments nucleate crystallisation.
| Property | Test method | Typical value |
|---|---|---|
| Melt flow rate at 190 °C / 2.16 kg | ASTM D1238 | 7.5 g/10 min |
| Density | ASTM D792 | 0.954 g/cm³ |
| Tensile yield strength | ASTM D638 | 25 MPa |
| Elongation at break | ASTM D638 | >100% |
| Flexural modulus | ASTM D790 | 1100 MPa |
| Vicat softening temperature | ASTM D1525 | 126 °C |
The tabulated values are supplier typical values from standard specimen testing. They do not represent guaranteed lot limits and they do not replace part testing. Tensile yield strength of 25 MPa and flexural modulus of 1100 MPa support rigid article design, but impact toughness, weld-line strength, and creep behaviour at elevated temperature remain application-specific. Elongation at break above 100% indicates ductile behaviour in short-time tensile loading; it does not predict long-term creep rupture. Notched Izod impact resistance should be measured on injection-moulded plaques using ASTM D256 or ISO 180, because moulded-in orientation and skin-core morphology differ from compression-moulded sheet.
Caps and closures represent a key application because the grade balances stiffness and flow. Top-load resistance is governed by sidewall geometry, knurl design, and wall thickness as much as resin modulus. For thin-wall containers, wall thickness below 0.8 mm may require higher melt temperatures near 230 °C and fast injection speeds to prevent short shots. Housewares and toys require drop-impact evaluation under end-use conditions; the material can withstand moderate deformation before yielding, but brittle failure can occur at sub-zero temperatures. The grade is not suitable for toys intended for prolonged outdoor UV exposure unless stabilised.
The principal difference from blow-moulding HDPE grades is that HS5407 has a melt flow rate above 5 g/10 min and therefore lacks the melt strength required for parison hang time and die swell control in extrusion blow moulding. Blow-moulding grades typically exhibit melt flow rates below 1.0 g/10 min and higher molecular weight tails that improve parison stability. Compared with pipe-grade HDPE, HS5407 has lower hydrostatic design basis and is not intended for pressure piping assessed under ISO 9080. Compared with high-flow injection-moulding grades with melt flow rates above 20 g/10 min, HS5407 provides greater resistance to stress cracking and impact, but it may require higher injection pressure in extremely thin-wall closures. The grade is not suitable for film extrusion, rotational moulding, or sheet requiring high melt strength.
Food-contact suitability is governed by the finished article and cannot be established from the resin datasheet alone. For United States applications, the polymer may be evaluated under FDA 21 CFR 177.1520, which covers olefin polymers as indirect food additives, provided the final article meets extraction limits in 21 CFR 177.1520(c). For European Union food-contact use, overall migration testing under EU Regulation 10/2011 and EC 1935/2004 is required with the intended food simulant. The grade is expected to comply with the heavy-metal restrictions of EU RoHS 2011/65/EU because no lead, cadmium, mercury, hexavalent chromium, PBB, or PBDE flame retardants are intentionally present. REACH registration under EC 1907/2006 is maintained by the supplier; downstream users must verify candidate-list SVHC obligations for imported articles.
| Regulatory framework | Designation | Typical verification |
|---|---|---|
| US food contact | FDA 21 CFR 177.1520 | Supplier certificate, extraction testing |
| EU food contact | EU Regulation 10/2011 | Overall migration under food simulant |
| EU chemicals | EC 1907/2006 | REACH registration, SVHC confirmation |
| EU hazardous substances | EU RoHS 2011/65/EU | No intentionally added restricted heavy metals |
Lot-specific certification should be requested for each production campaign. The certificate of analysis typically reports melt flow rate, density, and, when specified, tensile yield, flexural modulus, and Vicat softening temperature. Absence of a reported value on the certificate does not imply compliance; it indicates that the test was not ordered or was outside the supplier's standard lot release protocol. For safety-critical components, processors should retain retention samples and link batch numbers to processing records.
Storage in unopened original packaging in a dry, shaded area is recommended. The pellets can accumulate static charge during conveying; equipment should be grounded, and dust removal should be performed before feeding. The grade should be kept away from sources of heat above 50 °C to prevent pellet sintering. If contamination with incompatible polymers occurs, it is removed by purging rather than by direct addition because melt fractionation can produce hard spots in moulded parts. Processors should not rely solely on supplier typical values when qualifying HS5407 for load-bearing or safety-critical components. The grade is intended for injection moulding only.
