Extrusion blow moulding of UN-certified 1H1 jerricans in the 5–25 L range using Braskem HD3000N begins with a melt flow rate of 0.30 g/10 min under ASTM D1238 and a density of 0.949 g/cm³ under ISO 1183-1. The base formulation on production-scale accumulator-head machines is 100 phr HD3000N with 1.5–2.5 phr UV stabilizer masterbatch for outdoor warehousing and 1.0–2.0 phr pigment masterbatch; where the cargo is a flammable or static-accumulating solvent, 0.5–1.5 phr antistatic masterbatch is dispersed in the melt. Total non-resin additive loading is held below 4.0 phr to avoid measurable loss of environmental stress cracking resistance when tested under ASTM D1693-B in 10% Igepal. The blowing unit is a 60–75 mm grooved-feed extruder with L/D 24:1–30:1 and an accumulator head capacity of 2–5 kg; melt temperature is controlled at 180–220 °C, die temperature 185–210 °C, mould temperature 10–25 °C, blow air pressure 0.6–0.8 MPa, and blow ratio kept below 2.5:1 to maintain wall thickness distribution. Wall thickness for UN-rated jerricans is typically 1.5–3.0 mm, and closure bosses are calibrated during parison programming. Compliance is governed by UN Model Regulations Chapter 6.1, including hydrostatic pressure testing at 250 kPa/30 min for packing group I and 100 kPa/30 min for packing groups II and III, ADR 6.1, IMDG Code, REACH (EC) No 1907/2006, and EU Packaging Directive 94/62/EC heavy metal limits of ≤100 ppm combined Pb, Cd, Hg, and Cr VI. Terminal products are 5 L, 10 L, 20 L, and 25 L closed-head 1H1 jerricans for agrochemicals, industrial lubricants, detergents, and chemical intermediates.
Cosmetic and personal care bottles in the 150–1,000 mL range are produced from HD3000N on single-station or shuttle blow moulders with 35–55 mm extruders and L/D 24:1. The melt temperature is maintained at 170–195 °C to reduce odour and taste carryover below the upper processing limit of 220 °C; mould temperature is set at 8–15 °C, blow pressure 0.4–0.7 MPa, and cycle time 10–25 s. The base composition is 100 phr HD3000N with 0.8–1.5 phr colour masterbatch and 0.1–0.3 phr slip/antiblock masterbatch to prevent nesting on high-speed filling lines. Post-consumer recyclate is excluded from this configuration where skin-contact or food-adjacent claims are required. Compliance for the finished pack includes EU Cosmetic Regulation (EC) No 1223/2009, Regulation (EU) No 10/2011 with overall migration limit 10 mg/dm² for food-contact simulations, FDA 21 CFR 177.1520 for US-bound applications, and REACH Annex XVII. Terminal products include shampoo bottles, body wash bottles, lotion bottles, and cosmetic jars, with pinch-off depths limited to ≤0.8 mm to reduce leaker rates.
Automotive underhood fluid reservoirs blow moulded from HD3000N are constrained by long parison hang times when shot weight exceeds 1.5 kg. The melt flow rate of 0.30 g/10 min under ASTM D1238 provides the required melt strength, but parison sag becomes a limiting defect on continuous shuttle machines when extruder output exceeds 45 kg/h and die gap is not programmed. Processing setup for 3–5 L washer reservoirs uses 55–80 mm grooved-feed extruders, L/D 24:1–30:1, melt temperature 190–210 °C, accumulator head volume 2.5–6.0 kg, mould temperature 15–30 °C, blow air pressure 0.5–0.8 MPa, and cycle time 100–180 s. The formulation is 100 phr HD3000N with 1.0–2.0 phr carbon black masterbatch for UV stabilization and 0.5–1.0 phr antistatic masterbatch where flash retention is undesirable. Underhood exposure requires validation against OEM thermal-aging specifications; published data for this specific configuration is limited and must be generated through ISO 188 accelerated ageing and ISO 527-2 tensile retention. Terminal parts include windshield washer reservoirs, coolant overflow reservoirs, and auxiliary fluid containers in the 2–5 L range.
Industrial blow moulding of 11.3 L and 18.9 L water dispenser bottles from HD3000N is performed on long-stroke accumulator machines with screw diameters 70–90 mm, L/D 24:1–30:1, and clamp force 80–120 t. Melt temperature is kept at 180–200 °C to minimize thermally induced taste-and-odour compounds; mould temperature is 10–20 °C, blow ratio is 2.0:1, and cycle time for an 18.9 L bottle is 60–120 s. The compounding is 100 phr HD3000N with 1.0–1.5 phr blue masterbatch and 0.5–1.0 phr UV stabilizer masterbatch for outdoor storage. Recyclate is not used in this food-contact configuration unless a migration assessment verifies compliance. Regulatory requirements are Regulation (EU) No 10/2011 overall migration limit 10 mg/dm², FDA 21 CFR 177.1520, Regulation (EC) No 1935/2004 framework regulation, and heavy metal limits under EU Packaging Directive 94/62/EC. Terminal products include 11.3 L and 18.9 L water dispenser bottles, camp water storage containers, and laboratory reagent wash bottles where low extractables are required.
When post-consumer recycled HDPE is introduced into non-food detergent bottle lines, the extrusion blow moulding operating envelope shifts measurably relative to virgin HD3000N alone. On continuous shuttle machines with 50–65 mm extruders and L/D 24:1–28:1, melt temperature is reduced to 175–195 °C because recycled HDPE fractions typically contain lower-molecular-weight chains and reduce melt strength. Screens of 100–120 mesh or equivalent are installed upstream of the screen changer to trap contaminants; head pressure is monitored at 150–250 bar to detect screen blockage. The blend is 70–85 wt% HD3000N and 15–30 wt% clean HDPE post-consumer recyclate, with 1.0–2.0 phr colour masterbatch. Pre-drying of the recyclate at 70–80 °C for 2 h is required when storage exceeded 60% RH; without drying, surface moisture creates splay and pinholes at the pinch-off. Traceability of recyclate follows EN 15343:2007 and EuCertPlast certification where applicable. Finished products are 0.5–5 L non-food detergent, fabric softener, and household cleaner bottles; these packs are not assigned food-contact status under Regulation (EU) No 10/2011 unless migration testing demonstrates compliance.
Aggressive solvents and high-lift agrochemical formulations in the 0.5–5 L range are packaged in six-layer extrusion blow moulded containers in which HD3000N serves as the inner and outer structural skins. The layer distribution is typically 35–45 wt% HD3000N per skin, 2–4 wt% maleic anhydride grafted polyethylene tie resin, 2–5 wt% EVOH or polyamide barrier resin, and up to 20–30 wt% clean regrind in an inner structural layer. The coextrusion blow moulder is configured with 3–6 extruders; the HDPE extruders run at 190–210 °C, while EVOH is processed at 195–215 °C and must be purged promptly during interruptions to avoid decomposition above 230 °C. Die gap is 0.8–1.2 mm, blow ratio is 2.2:1, and total wall thickness is 1.2–2.0 mm. Barrier validation is tested by oxygen permeation under ASTM D3985 and hydrocarbon permeation under ASTM D2684; for UN-certified packs, the container also passes UN Model Regulations Chapter 6.1 hydrostatic pressure testing. Terminal products include 1 L, 2 L, and 5 L solvent bottles, agrochemical packs, and technical chemical containers where barrier performance replaces post-mould fluorination.

Braskem HDPE HD3000N is a high-molecular-weight, broad-molecular-weight-distribution high-density polyethylene resin developed for extrusion blow molding of rigid packaging and technical parts. The grade is supplied as cylindrical pellets. Its nominal density is 0.949 g/cm³ measured under ISO 1183-1:2019, and its melt flow rate is 0.30 g/10 min under ISO 1133-1:2022 at 190°C with a 2.16 kg load. This low melt flow rate indicates high melt viscosity and high parison hang strength, which separate HD3000N from high-flow HDPE injection grades used for thin-wall containers.
| Property | Test method | Nominal value |
|---|---|---|
| Density | ISO 1183-1:2019 | 0.949 g/cm³ |
| Melt flow rate, 190°C/2.16 kg | ISO 1133-1:2022 | 0.30 g/10 min |
| Tensile yield strength | ISO 527-2 | 27 MPa |
| Elongation at break | ISO 527-2 | >800% |
| Flexural modulus | ISO 178 | 1,100 MPa |
| Vicat softening temperature, A50 | ISO 306 | 126°C |
| Environmental stress crack resistance, F50 | ASTM D1693-15 Condition B, 100% Igepal | >600 h |
The mechanical profile reflects a balance between stiffness and environmental stress crack resistance. The flexural modulus of 1,100 MPa is lower than that of denser HDPE grades with densities of 0.955–0.965 g/cm³, but the ESCR F50 above 600 h under ASTM D1693-15 Condition B is higher than that of many general-purpose blow molding resins with melt flow rates in the 0.7–1.0 g/10 min range. Bulk density of the pellets is typically 0.54–0.58 g/cm³, and storage below 40°C avoids pellet agglomeration in warm warehouses.
The broad molecular weight distribution produces a distinct shear-thinning response in extrusion blow molding. Capillary rheometry at 190°C shows decreasing viscosity from the zero-shear plateau into the 100–1,000 s⁻¹ die shear rate range. At a die shear rate of 500 s⁻¹, sufficient extensional viscosity is retained to resist sag during parison transfer. Published data for this specific configuration is limited, but production-scale trials on grooved-feed extruders with 80–120 mm screw diameter and 24:1 L/D have shown stable output at screw speeds from 30–70 rpm.
Compared with narrow-molecular-weight-distribution metallocene HDPE grades, HD3000N tolerates higher shear rates before sharkskin appears. Extrudate swell in broad-MWD blow molding HDPE is commonly observed between 35% and 60% at die shear rates of 100–500 s⁻¹, which requires die gap settings of 1.5–3 times final wall thickness. Die lip build-up can be reduced with fluoropolymer-based processing aid at 200–500 ppm. Excessive screw speeds above 80 rpm can raise melt temperature above 220°C and lower melt strength on long accumulator-head cycles.
Extrusion blow molding of HD3000N is run on shuttle or accumulator-head machines. A barrier screw with 24:1 to 30:1 L/D and a compression ratio of 2.5:1 to 3.0:1 is used. Temperature settings rise from 170°C in zones 1–2 to 200°C–215°C at the die. Die head temperatures below 190°C increase melt pressure and create unmelts in the parison wall, while sustained melt temperatures above 230°C reduce parison hang strength and increase degradation risk during interruptions.
HDPE is nonhygroscopic. Surface condensation at relative humidity above 60% can produce splay, so hopper drying at 75°C–80°C for 1–2 h is sufficient. Blow molds are held at 10°C–30°C; lower mold temperatures shorten cycles but increase residual stress in thick handle sections. Blow air pressure from 0.6 MPa to 0.9 MPa and blow-up ratios of 2:1 to 4:1 are typical. Parison programming with 50- or 100-point wall-thickness control is used for nonuniform cross-sections. Filtration through a 40/80/40 screen pack is common; melt pressure at the head should remain below 35 MPa to limit shear heating.
During accumulator-head cycles, parison hang time from die exit to mold closing is commonly 5–15 s for large parts. At 230°C, sag becomes measurable as wall thinning in the lower parison zone. Programmable wall-thickness control compensates by closing the die gap by 0.5–1.5 mm in the final parison segments. Shot-to-shot temperature variation at the die should be held within ±2°C. During interruptions exceeding 10 min, the barrel is purged with low-melt-flow-rate LDPE at 190°C to limit stagnant resin degradation.
Large-volume containers for surfactant-based cleaners, agricultural chemicals, and non-halogenated solvents are produced from HD3000N on accumulator-head machines with shot capacities from 5 kg to 20 kg. The pinch-off weld and handle junctures are critical. Production-scale failure modes include pinhole leaks at the flash line when parison velocity exceeds 100 mm/s and cold slugs from unmelted pellets. For 20 L–30 L jerrycans, molders set accumulator drop speed to avoid foldover and maintain clamp force from 60 metric tons to 100 metric tons depending on tooling area. Drop impact testing under ISO 2248 or UN/DOT qualification is used; the high ESCR and high-molecular-weight fraction reduce brittle failure along the pinch-off line.
HD3000N is accepted for continuous contact with dilute aqueous acids, bases, and saturated aliphatic hydrocarbons at ambient temperature. It is not suitable for strong oxidizing acids, halogens, or aromatic solvents at elevated temperature. Swelling in toluene at 23°C can exceed 5 wt% within 72 h, reducing ESCR and burst pressure. The solubility parameter distance between HDPE and toluene is small enough to permit noticeable uptake. For agricultural formulations containing more than 10% xylene or cyclohexanone, compatibility testing under ASTM D543-21 is required before production.
Untreated HDPE surfaces have a surface energy near 32 dyn/cm measured under ISO 8296; adhesion of labels and inks requires pretreatment to 38–42 dyn/cm. Flame treatment above 42 dyn/cm can embrittle the surface and reduce pinch-weld strength. Fatty acid amide slip additives above 0.2 wt% are avoided in high-stress closures and handles because they lower weld strength. The grade is not recommended for contact with strong oxidizing acids above 30% concentration at temperatures above 40°C.
At 0.30 g/10 min, HD3000N is unsuitable for thin-wall injection molding. High-flow HDPE grades with melt flow rates of 20–50 g/10 min achieve substantially longer spiral flow lengths at the same injection pressure. Bimodal pipe resins may have similar melt flow rates but different comonomer placement and higher resistance to slow crack growth. HD3000N therefore occupies an intermediate position: lower stiffness than high-density injection grades, higher ESCR than general-purpose blow molding grades, and lower slow crack growth resistance than PE100 pipe materials.

Food-contact use of HD3000N is generally supported by the olefin polymer provisions of FDA 21 CFR 177.1520 when the final article is manufactured under specified conditions. In the European Union, articles must comply with Regulation (EU) 10/2011 as amended by Regulation (EU) 2020/1245, including the overall migration limit of 10 mg/dm² for food-contact plastics. The grade is expected to meet REACH and RoHS heavy-metal restrictions, but converters should obtain lot-specific certificates of compliance for SVHC content and dual-use additives.
Pharmaceutical packaging applications require additional extractables and leachables screening under USP 661.1 or Ph. Eur. 3.1.3. Published data for this specific grade may be limited in pharmaceutical registrations, and such applications should be qualified case-by-case with actual container closure systems.
Color concentrates and processing aids should be polyethylene-based; carrier resins with melt flow rates above 20 g/10 min can reduce parison hang strength at loadings above 2 wt%. Typical color masterbatch loading from 2 wt% to 4 wt% shifts the apparent melt flow rate upward but does not eliminate die lip build-up. Hot-plate welding of HD3000N requires surface temperatures of 200°C–215°C, heating times of 20–30 s, and joining pressure of 0.1–0.3 MPa; removal of oxidized surface skin is necessary to prevent brittle weld lines.
