For monolayer extrusion blow moulding of household and industrial chemical containers, HDPE 006964EG is processable on accumulator-head machines with barrel diameters between 70 mm and 120 mm and screw L/D ratios of 24:1 to 30:1. Barrel temperature profiling is normally maintained between 180 °C and 210 °C, with the adapter and die head held at 205–220 °C to control parison sag; melt temperature measured at the die should not exceed 230 °C because oxidative chain scission accelerates at higher residence times. A die land length of 15–20 × the die gap is used to stabilize parison swell and reduce melt fracture in the shear rate range 100–500 s⁻¹. Mould temperature is typically held at 10–25 °C using chilled water circuits to reduce post-mould shrinkage. Under these conditions, the resin can be processed without predrying when surface moisture is below 0.05 wt%; otherwise, predrying at 80 °C for 2–3 h with a desiccant dryer is required. For household detergent and bleach bottles from 500 mL to 5 L, the standard formulation is 100 wt% virgin HDPE 006964EG or 80 wt% virgin plus 20 wt% closed-loop regrind, with 0.5–2.0 wt% colour masterbatch added when opacity is required. Finished articles intended for aqueous, fatty, and low-alcohol food contact fall under FDA 21 CFR 177.1520 and EU Regulation (EU) No 10/2011, where overall migration must remain below 10 mg/dm² under the specified simulant and time-temperature conditions. Cycle times typically range from 8 s to 25 s depending on part weight and accumulator capacity.

UN-certified jerricans and tight-head containers between 10 L and 30 L impose a critical processing conflict between the high melt strength required for parison stability and the low frozen-in stress required for drop impact at -18 °C. The accumulator head should be configured with a parison programmer capable of 30–64 point wall thickness profiling, because the pinch-off zone and shoulder sections require a wall thickness 40–60% greater than the sidewall to survive drop test energy. Drop impact compliance is assessed under UN Model Regulations Chapter 6.1, ADR 6.1.4.8, or 49 CFR Part 178; conditioning at -18 °C for 24 h followed by drop from 1.2 m onto a rigid steel plate is the standard protocol for Packing Group II liquids. Environmental stress crack resistance is the dominant material property; for HDPE blow moulding grades, ASTM D1693 Condition B in 10% Igepal CO-630 routinely reports F50 values above 100 h, but published data for this specific grade should be confirmed against the supplier’s lot certificate. Screw speed should be limited to 30–60 min⁻¹ on a 90 mm extruder to avoid excessive shear heating, which lowers melt viscosity and increases wall-thickness variation. Apparent die land shear rate is maintained below 500 s⁻¹ to remain below the critical shear stress of approximately 0.15 MPa, although grade-specific validation is required. Blow air pressure is set between 0.6 MPa and 0.9 MPa, with pre-blow delayed until the parison reaches 85–90% of the mould length. The finished jerrican is additionally evaluated for stack load at 40 °C for 28 days with a top-load of 2.5 kN, as required by ISO 22308 for UN packaging. Regrind content should not exceed 25 wt% unless validated for drop performance, as higher fractions reduce ESCR and increase brittleness at low temperature. The process window should not operate below 195 °C melt temperature if weld-line integrity in the pinch-off tail is to be maintained.
Where HDPE 006964EG is converted via flat-die sheet extrusion into 2–8 mm substrate for plug-assist thermoforming, the dominant operational constraint is the narrow temperature band between sag resistance and plug mark formation. A 90–120 mm single-screw extruder with a barrier screw and L/D 30:1 drives the melt through a gear pump and a coathanger die with an adjustable restrictor bar; melt temperature at the die inlet is typically 200–215 °C. The vertical three-roll stack is set with a first roll temperature of 70–80 °C and a second roll temperature of 80–90 °C to control sheet crystallinity, while haul-off speed is adjusted to maintain a sheet width tolerance of ±0.5%. In-line edge trim and skeletal scrap are reprocessed at 15–30 wt% of total feed, with the balance virgin HDPE 006964EG; regrind fractions above 30 wt% increase gel formation and gauge drift due to cross-contamination of polypropylene from upstream handling. Thermoforming is then performed at sheet surface temperatures of 165–185 °C; below 160 °C, HDPE from this molecular weight class exhibits insufficient extensibility and produces microvoids. Plug assist geometry with a closed-cell foam plug and 0.15–0.30 MPa forming vacuum is preferred. The resultant trays, dunnage sheets, and drum liners are assessed for tensile elongation under ASTM D638 and flexural modulus under ASTM D790, with reference HDPE values of 700–900 MPa flexural modulus; exact values for 006964EG must be confirmed. Food-contact sheet intended for frozen foods must satisfy EU No 10/2011 total migration limits and should avoid recycled content above 30 wt% if traceability under EC No 282/2008 is to be maintained.
Agricultural chemical containers from 1 L to 20 L produced in HDPE 006964EG are subjected to inline surface fluorination when the packaged active ingredient solubility parameter approaches that of the polymer. The barrier treatment uses a gas mixture of 0.05–0.2 vol% F₂ in nitrogen at 20–60 °C for 15–120 s after moulding, producing a surface fluorinated layer 0.1–10 µm thick; X-ray photoelectron spectroscopy data typically show 5–20 atomic% fluorine at the immediate surface. This conversion lowers permeation rates for aromatic hydrocarbons and halogenated solvents, but excessive treatment embrittles the inner wall and reduces pin-hole burst strength by 10–30%. The process conflict is the trade-off between barrier improvement and weld-line sealing at the pinch-off; fluorination must be performed before neck finishing or after trimming to avoid surface contamination interfering with cap torque retention. Typical formulations include 0.5–1.5 wt% UV stabilizer masterbatch and 20–30 wt% in-house regrind, but regrind content above 30 wt% creates molecular weight degradation and reduces ESCR below acceptable values for paraquat or glyphosate formulations. The finished article is tested according to UN Chapter 6.1 drop and stack protocols and, where applicable, OECD Guideline 432 for packaging environmental fate; no harmonised fluorination standard exists, so converter data packs are required. Terminal products include jerricans and jugs for selective herbicides, systemic insecticides, and solvent-based emulsifiable concentrates, where shelf-life leakage requirements are specified by the fill customer.

To convert HDPE 006964EG into closed-head and open-head drums between 120 L and 220 L, the parison weight can exceed 9 kg, requiring accumulator heads with shot capacity above 15 L and extruder diameters of 120–150 mm. Screw speed is typically reduced to 25–45 min⁻¹ to avoid shear heating; melt temperature at the die is kept at 200–215 °C. Wall thickness distribution is controlled by a linear encoder tied to the mould carriage, not by free parison sag. Cooling time for HDPE 006964EG in a 200 L drum can range from 120 s to 240 s depending on ambient temperature and mould cooling channel turbulence; mould temperature is maintained at 8–15 °C using ethylene glycol-water mixtures. Post-mould shrinkage at the top thread can exceed 0.8%; therefore, thread calibration and cooling fixtures are fixed for 30–60 s after ejection. Drop impact compliance under UN 6.1.5.3 for Packing Group II liquids is assessed at -18 °C after 24 h conditioning. The use of external layers with 2–4 wt% carbon black masterbatch is common for UV-exposed storage; however, carbon black above 4 wt% can mask surface defects in vision systems. Published data for this specific drum configuration is limited, so production trials with the supplied lot should validate top-load, weld-flash thickness, and hydraulic pressure settings.
Corrugated HDPE drainage pipe conforming to EN 13476-1 or AASHTO M294 is constrained by the 0.2–0.6 dg/min melt flow class of this grade; published data for this specific configuration is limited, and converter validation is required before production.

Amco Plastic Materials HDPE 006964EG is an unfilled high-density polyethylene resin distributed under a supplier-specific material code. The designator 006964EG does not contain a published melt flow rate, density, or additive declaration, so incoming inspection and process development should be initiated from the lot-specific certificate of analysis supplied with the shipment. Density classification for HDPE is at or above 0.941 g/cm³ when tested according to ASTM D1505 or ISO 1183-2. The product is therefore in the semicrystalline polyolefin class with higher density and typical stiffness than low-density polyethylene and linear low-density polyethylene. The suffix EG is not an industry-standard grade suffix and must not be interpreted as a food-contact, potable-water, or extrusion-grade certification.
Because no public third-party datasheet exists for HDPE 006964EG at the time of writing, all property ranges in this document are general HDPE homopolymer reference envelopes from ASTM, ISO, and supplier literature. They are not lot-specific performance guarantees for 006964EG. Parameters that should be requested from the distributor include melt mass-flow rate at 190 °C/2.16 kg according to ASTM D1238-23 or ISO 1133-1:2022, density, tensile yield strength according to ASTM D638-14 or ISO 527-2:2012, flexural modulus according to ASTM D790-17 or ISO 178:2019, notched Izod impact according to ASTM D256-23, and heat deflection temperature according to ASTM D648. If the resin is intended for regulated use, a written compliance statement for the finished article is also required.
Because the exact melt flow rate is not published, barrel settings cannot be fixed from a certified grade datasheet. Initial trials on a hydraulic injection molding machine with a general-purpose 20:1 L/D screw and a nonreturn valve should be conducted with a reverse barrel profile of 180–230 °C from feed to nozzle and a mold temperature of 10–40 °C. This range is broad because HDPE homopolymers with melt flow rates from 0.2 g/10 min to 20 g/10 min at 190 °C/2.16 kg can show large differences in pressure requirement and shear heating. A lot with a melt flow rate below 1 g/10 min usually requires the upper end of the melt temperature range and reduced screw speed to avoid torque-limited screw recovery. A lot above 8 g/10 min often requires lower melt temperature and longer hold pressure to control flash and sink.
Moisture handling is generally straightforward for high-density polyethylene. Drying is not required when surface moisture is below 0.05 wt%. If the resin has been stored in unheated conditions or exposed to condensation, desiccant drying at 65–80 °C for 1–2 h removes surface water. Continuous melt temperature above 260 °C or residence time above 5 min should be avoided because oxidative chain scission can reduce molecular weight and cause yellowing. On production-scale injection molding lines, HDPE lots with density near 0.960 g/cm³ and low melt flow rate have produced gate blush and elevated injection pressure when nozzle temperature is below 210 °C; raising the nozzle zone to 220–230 °C and increasing cushion to 5–8 mm reduces short shots but may increase cycle time. These observations are generic HDPE processing behavior and must be confirmed for each lot of 006964EG.
Hold pressure should be set at 50–75% of peak injection pressure and applied for 8–15 s depending on wall thickness. Screw decompression should not exceed 3–5 mm to avoid air entrapment and flow marks. Back pressure in the range of 0.5–1.5 MPa improves melt homogeneity but raises melt temperature, particularly when shot size is small and residence time exceeds 3 min. For extrusion, a capillary rheometer scan at 190–230 °C and shear rates from 10 s⁻¹ to 1000 s⁻¹ is needed to estimate screw torque and die pressure. A single melt-flow point is insufficient to differentiate HDPE grades with similar melt mass-flow rate but different molecular weight distribution.
Application screening for HDPE 006964EG typically begins with rigid packaging, crates, caps, closures, industrial containers, and technical parts that do not require sustained high temperature. The general HDPE homopolymer envelope provides tensile yield strength of 20–30 MPa and flexural modulus of 800–1600 MPa. These reference values support load-bearing packaging with stacking resistance, but published data for this specific configuration is limited. For thin-wall injection-molded parts, flow length and wall thickness must be related to the lot-specific melt flow rate; for thick-wall extruded sheet or profile, a lower melt flow rate and higher melt strength may be preferred. The converter should not infer suitability from the HDPE classification alone.
Compared with HDPE grades commonly used in blow molding, this material may be evaluated for extrusion and injection processes only after rheology testing. The lack of a published product datasheet means that a reference-grade comparison is the most reliable method for determining whether 006964EG performs closer to a fractional-melt HDPE or a high-flow injection HDPE. A melt viscosity curve generated by capillary rheometry at 190 °C and 230 °C can be overlaid on the viscosity curve of a known production resin. If the viscosity at 100 s⁻¹ falls within ±20% of the reference grade, initial process settings can be transferred with appropriate caution. No universal tolerance exists; an internal acceptance criterion should be set from process capability data.
When HDPE 006964EG is evaluated as a replacement for linear low-density polyethylene, low-density polyethylene, or polypropylene, the comparison must be based on density, stiffness, shrinkage, environmental stress crack resistance, and thermal resistance. The unfilled polyolefin reference table below is drawn from published ASTM and ISO methods and does not provide certified lot values for 006964EG.
| Property | Method | HDPE | LDPE | LLDPE | PP |
|---|---|---|---|---|---|
| Density | ASTM D1505 | 0.941–0.970 g/cm³ | 0.917–0.930 g/cm³ | 0.916–0.940 g/cm³ | 0.900–0.915 g/cm³ |
| Melt flow rate | ASTM D1238 | 0.2–20 g/10 min at 190 °C/2.16 kg | 0.2–70 g/10 min at 190 °C/2.16 kg | 0.5–25 g/10 min at 190 °C/2.16 kg | 1–35 g/10 min at 230 °C/2.16 kg |
| Tensile yield strength | ASTM D638 | 20–30 MPa | 8–12 MPa | 8–15 MPa | 25–38 MPa |
| Flexural modulus | ASTM D790 | 800–1600 MPa | 150–400 MPa | 200–500 MPa | 1000–1800 MPa |
| Notched Izod impact | ASTM D256 | 30 J/m to no-break, grade-dependent | no-break typical | no-break typical | 20–100 J/m |

The central difference in rigid packaging is the combination of modulus and mold shrinkage. HDPE 006964EG, if it falls within the published HDPE density envelope, will generally provide higher flexural modulus than LLDPE and LDPE but lower low-temperature impact strength. The ductile-to-brittle transition for HDPE is typically at or above -50 °C, but depends on comonomer content and molecular weight. Compared with polypropylene, HDPE offers a lower heat deflection temperature of 65–80 °C at 0.455 MPa and generally better stress-crack resistance in many detergent and hydrocarbon environments. A converter replacing PP with HDPE must adjust for higher mold shrinkage and lower melt temperature; a converter replacing LLDPE with HDPE must assess stack compression resistance against the loss of tear strength and clarity. For pipe or conduit applications, HDPE is commonly evaluated by ISO 9080 long-term hydrostatic strength and ASTM D2837 pressure rating; such data are product-specific and not available from a distributor code alone.
Food-contact or potable-water use of HDPE 006964EG requires explicit supplier documentation. The distributor code alone does not confirm compliance with FDA 21 CFR 177.1520, Regulation (EU) No 10/2011, or NSF/ANSI 61. The following checklist should be applied at incoming inspection when a regulated application is claimed.
| Regulatory area | Standard or requirement | Verification action |
|---|---|---|
| US food contact | FDA 21 CFR 177.1520 | Request supplier food-contact letter or lot-specific certification; confirm extraction conditions for the intended use. |
| EU food contact | Regulation (EU) No 10/2011 | Review overall migration and specific migration limit documentation; verify batch-specific formulation disclosure. |
| Drinking water | NSF/ANSI 61 or NSF/ANSI 51 | Confirm listing status for the exact grade designation; do not transfer a generic HDPE listing. |
| REACH | Regulation (EC) No 1907/2006 | Check safety data sheet for SVHC content and registration obligations for the supplied article. |
| RoHS | Directive 2011/65/EU | Verify absence of restricted substances; obtain declaration if electrical or electronic equipment accessory applications are intended. |
| California Prop 65 | California Safe Drinking Water and Toxic Enforcement Act | Check for listed substances; request supplier certificate if California distribution is planned. |
Without such documentation, the resin should be treated as general-purpose and excluded from food-contact, medical, or potable-water applications. Chemical compatibility for industrial containers should be verified by immersion testing according to ASTM D543 or ISO 4433 using the actual stored liquid at the maximum service temperature. HDPE is not recommended for continuous exposure to strong oxidizing acids, aromatic hydrocarbons, or chlorinated hydrocarbons under stress.
Incoming lot verification for HDPE 006964EG should compare density, melt flow rate, and tensile yield strength against an internal approved-lot reference. A density shift of ±0.002 g/cm³ may indicate an inadvertent blend of LLDPE or LDPE or a change in comonomer content. A melt-flow-rate deviation greater than ±15% from the approved target should trigger a process capability review because it can alter filling speed, packing behavior, part mass, and screw recovery time. These are not specification limits but internal control thresholds derived from standard injection-molding process capability studies.
On equipment with in-mold pressure sensors, the cavity pressure integral should be monitored rather than injection pressure alone. HDPE lots with equivalent density but different molecular weight distribution can produce identical peak injection pressure and still differ in gate seal time and sink resistance. A stable process should maintain cavity pressure peak within ±5 MPa and cavity pressure integral within ±10% of the qualified reference. Regrind content should be controlled at 20–30% for tight-tolerance parts unless a formal process capability study demonstrates equivalent dimensional stability. Do not blend HDPE 006964EG with polypropylene or PET without dedicated separation and cleaning because the resulting morphology can create delamination and brittleness.
