Extrusion blow molding of rigid household and industrial chemical containers uses Braskem HDPE GM5010T2B as the primary structural resin. The grade is processed on single-screw extruders with L/D ratios between 24:1 and 30:1, fitted with barrier screws and Maddock mixing elements to achieve melt temperature homogeneity within ±3°C at the die exit. Regulatory compliance for this container category aligns with UN Model Regulations Chapter 6.1 for dangerous goods packaging where applicable, alongside REACH Annex XVII restrictions on phthalates and heavy metals migrating from container walls into aggressive liquid media. For non-hazardous household chemicals, the governing standard is DIN EN 15507:2017, which specifies stackability, drop resistance at -18°C, and stress cracking thresholds for detergent bottles containing surfactants. The resin addition ratio in monolayer configurations ranges from 97.5 wt% to 99.2 wt%, with the balance composed of processing stabilizers, external lubricants, and optional UV stabilizer masterbatch dosed at 0.8–1.6 wt% for outdoor storage exposure. Wall thickness distribution across container bodies is controlled by die gap programming synchronized to parison length; typical wall thickness for a 1 L bottle averages 0.7–0.9 mm, with corner thinning limited to < 15% of nominal wall. Terminal product types include laundry detergent bottles, multi-surface cleaner containers, bleach bottles with post-consumer recycled content blends, and industrial solvent jerrycans up to 10 L capacity.
Pharmaceutical HDPE bottle production using GM5010T2B is dominated by the relationship between environmental stress cracking resistance (ESCR) and molded-in residual stress. The governing pharmacopoeial test is USP <661.1> for polymeric packaging components, supplemented by Ph. Eur. 3.1.3 for polyolefines and ASTM D1693 for ESCR, condition B, with specimens notched to 0.35 mm depth and immersed in 100% Igepal CO-630 at 50°C. Compliance with FDA 21 CFR 177.1520(c) for olefin polymers in food and drug contact is mandatory for oral solid dose containers. The resin addition ratio in pharmaceutical bottle compounds varies with the inclusion of antistatic agents and processing aids; GM5010T2B typically constitutes 98.0–99.5 wt% of the compound, with antistatic masterbatch loaded at 0.3–1.0 wt% and slip/antiblock modifiers limited to < 0.5 wt% to avoid extractables exceeding USP <661.1> thresholds. Extrusion blow molding on shuttle machines with double-station tooling operates at parison temperatures between 185°C and 200°C, and mold temperatures held at 8–14°C to accelerate crystallinity development; bottle body wall thickness for a 60 mL unit is specified at 0.5–0.65 mm. Terminal product categories include HDPE vials for tablets, liquid syrup bottles with neck finishes conforming to DIN 18322-1, and desiccant-lined closure systems for hygroscopic APIs.
Cosmetic and personal care rigid packaging represents a downstream segment where GM5010T2B is processed under conditions that prioritize surface gloss, wall thickness consistency, and compatibility with alcohol-based formulations. Compliance is anchored to ISO 22715:2006 for cosmetic packaging quality requirements, EU Cosmetic Products Regulation (EC) No 1223/2009 for substance migration from primary packaging, and DIN EN 13430:2004 for material recycling compatibility of the finished package. Formulation addition ratios for this segment frequently integrate post-industrial regrind derived from trimmed flash and deflashed bottoms; the GM5010T2B virgin resin content is maintained between 80 wt% and 95 wt%, with regrind limited to 10–20 wt% and pearlescent or opaque color masterbatch dosed at 1.5–2.5 wt%. Processing on continuous shuttle blow molding machines with parison wall thickness profiling demands melt pressures at the extruder head between 18 MPa and 25 MPa; extruder screw speed is restricted to 35–55 rpm to prevent excessive shear heating that degrades the color dispersion quality. Terminal product types include shampoo bottles, body wash containers with side seams, conditioner tubes, and layered cosmetic jars where the HDPE layer provides the structural backbone.
Fabrication of automotive washer fluid reservoirs and auxiliary fluid containers using GM5010T2B involves stringent dimensional stability requirements under thermal cycling and exposure to glycol/water mixtures and surfactant-based washer concentrates. Conformance to ISO 16750-4:2023 for climate loads, SAE J2044 for fluid compatibility of plastic reservoirs, and DIN 73411 for coolant expansion tank design parameters forms the compliance matrix. The resin addition ratio in this application segment is typically 100 wt% GM5010T2B for monolayer structures, or reduced to 60–80 wt% in multi-layer parison configurations where barrier layers of polyamide or EVOH are coextruded, with adhesion promoted by maleic anhydride grafted tie resins at 1.5–3.0 wt% of the total composite thickness. Blow molding of these components requires high clamp force presses ranging from 80–160 tons to counteract flash formation across complex parting lines; mold cooling channels are designed with Reynolds numbers above 10,000 to ensure turbulent flow and efficient heat extraction from walls averaging 2.0–3.5 mm thickness. Terminal product categories include windshield washer fluid bottles with integrated level sensors, radiator overflow bottles, and heavy-duty truck coolant reservoirs with ultrasonic weld bosses.
Large-part blow molding of industrial drums and intermediate bulk container liners using GM5010T2B is governed by the need for prolonged environmental stress cracking resistance under continuous hoop stress. The governing standards are UN Model Regulations Chapter 6.5 for IBCs, ISO 16101:2004 for compatibility testing of plastics packagings with liquid chemicals, and ADR/RID Chapter 6.1 for dangerous goods transport containers. Formulation addition ratios for monolayer 120 L open-head drums typically include 99.0–99.7 wt% virgin GM5010T2B with the balance comprising antioxidant packages based on hindered phenols and phosphites; UV-stabilized grades for outdoor storage incorporate carbon black masterbatch at 2.0–2.5 wt%. The extrusion blow molding process uses accumulator-head machines with screw diameters from 90 mm to 150 mm, shot capacities exceeding 12 kg, and die gap control resolution of 0.1 mm across 128 circumferential points. Component wall thickness at the drum base corner is specified at 5.0–8.0 mm, transitioning to 2.5–3.5 mm at the sidewall mid-height. Terminal product categories include open-head steel-reinforced plastic drums, closed-head chemical transport drums with 2-inch buttress threads, and rigid IBC inner bottles for corrosive liquids.
Edible oil and dairy product container production with GM5010T2B is characterized by a compliance framework that prioritizes migration limits and sensory neutrality. The governing standards include EU Regulation (EU) No 10/2011 for plastic food contact materials, with overall migration limits of 10 mg/dm² for liquid simulants, and FDA 21 CFR 177.1520 for olefin polymers in contact with aqueous, acidic, and fatty foods. Additional organoleptic testing follows DIN 10955:2023 for sensory evaluation of food contact materials. The formulation addition ratio for monolayer food bottles using this grade is 99.0–99.8 wt%, with process stabilizer concentrations not exceeding 0.2 wt% and slip agents limited to erucamide at 200–500 ppm to minimize extractable contribution. Processing parameters on high-output wheel blow molding machines maintain melt temperatures at the accumulator head between 190°C and 210°C; the parison swell ratio is controlled within 1.8–2.2 to achieve wall thickness reproducibility of ±0.05 mm on 1 L bottle bodies. Terminal product types include UHT milk bottles, edible oil jugs with handle pinch, vinegar containers, and dry food jars with induction-sealable neck finishes conforming to ISO 2852 for clamp fittings.
Diagnostic reagent and laboratory chemical packaging constitutes a specialized downstream segment where GM5010T2B is converted into containers requiring leak-proof performance under both positive and negative internal pressures. Compliance requirements in this segment reference ISO 11418-1:2016 for pharmaceutical preparation containers, DIN EN ISO 13130:2011 for laboratory apparatus, and ASTM D4991-07(2023) for leak testing of empty rigid containers under differential pressure. The resin addition ratio in diagnostic container formulations rests at 98.5–99.5 wt%, with antistatic agent additions not exceeding 0.5 wt% to control surface resistivity below 10¹¹ Ω/sq per ASTM D257, particularly for containers used in proximity to flammable solvent transfer. Production on single-station blow molding machines with mold temperature set points between 6°C and 10°C requires parison thickness profiling that accounts for the container's flat front and back panels, where wall thinning at corner transitions is limited to < 12% of nominal wall thickness. Terminal product types include reagent bottles with tamper-evident caps, buffer solution containers with graduated markings, and specimen transport bottles used in diagnostic laboratory networks.

Braskem HDPE GM5010T2B is a high-molecular-weight high-density polyethylene supplied as pelletized feedstock for extrusion blow moulding of rigid hollow parts. The grade is positioned for large-format containers, industrial packaging, and thin-wall technical bottles in which environmental stress-crack resistance, parison melt strength, and reproducible wall-thickness control govern production yield. Representative nominal values in industrial specifications place the melt flow rate in the range of 0.20–0.30 g/10 min at 190 °C/2.16 kg when tested according to ASTM D1238 or ISO 1133-1, and the density in the range of 0.950–0.955 g/cm³ when tested according to ASTM D1505 or ISO 1183-1. The resin belongs to the upper molecular weight segment of HDPE blow moulding grades; the low melt flow rate relative to general-purpose grades increases die swell, sag resistance, and accumulator-head pressure.
The polymer structure combines a high weight-average molar mass with controlled short-chain branching. This configuration raises low-shear viscosity more than high-shear viscosity, which increases parison stability without proportionally increasing die pressure at typical blow moulding shear rates. The material is supplied with a processing stabilizer package sufficient for conventional extrusion, but residence times above 230 °C consume antioxidant reserves and accelerate oxidative chain scission. The grade should therefore be processed within a defined melt temperature envelope rather than at the upper thermal limits used for lower-viscosity HDPE grades.
General-purpose blow moulding HDPE grades often carry melt flow rates of 0.35–0.45 g/10 min and are formulated for high-output domestic bottles. GM5010T2B falls below this melt flow range, which raises the high-molecular-weight tail responsible for slow crack growth resistance. Under ASTM D1693 condition B, the bent-strip environmental stress-crack resistance of the resin is substantially longer than that of standard 0.35 melt index grades. Published industrial data for this category indicates an ESCR value commonly exceeding 600 h, whereas conventional blow moulding grades may fail below 100 h at equivalent notched-specimen conditioning. The difference becomes critical when containers are exposed to surfactants, agricultural chemicals, aliphatic hydrocarbons, or cyclic top-load fatigue.
The density of GM5010T2B remains within the standard HDPE blow moulding window, but the modulus penalty associated with high-ESCR resins is restrained. Flexural modulus values in the range of 1,050–1,200 MPa are typical for this product segment, compared with 1,150–1,300 MPa for stiffer low-molecular-weight blow moulding grades. Tensile yield strength is generally reported in the range of 26–30 MPa under ASTM D638 or ISO 527-2, and elongation at break ordinarily exceeds 600%. The trade-off is lower melt flow and higher extruder backpressure, which requires processing on equipment rated for high-molecular-weight material rather than on small bottle machines designed for 0.35 g/10 min resins.

On accumulator-head machines fitted with 24:1 to 30:1 L/D grooved-barrel extruders, the material is often processed with a melt temperature profile of 180–220 °C measured at the die adapter. The lower bound is set by torque demand and melt fracture; the upper bound is set by thermo-oxidative degradation and loss of parison melt strength. Die head temperatures are typically held 5–10 °C below the adapter temperature to increase melt viscosity at the die exit and reduce sag. At die land shear rates above approximately 300 s⁻¹, surface melt fracture becomes visible as sharkskin on thick parisons; increasing die temperature or reducing extruder speed resolves the condition without major change in extrudate swell.
Moisture control is generally not required below 60% ambient relative humidity. If pellets are stored in open outdoor bays or silos and surface moisture exceeds approximately 0.02 wt%, hopper drying at 70–80 °C for 2–3 h using desiccant air with a dew point below -20 °C prevents steam splay and internal bubble formation. The pellets should not be exposed to temperatures above 40 °C for prolonged periods before extrusion because stabilizer diffusion and pellet agglomeration may occur. Processors using central vacuum conveying systems should confirm that conveying air dew point is below 5 °C when ambient humidity exceeds 70%.
Colour masterbatches based on high-melt-flow LLDPE carriers can reduce parison melt strength when added above 2 wt%. Carriers with melt flow rates above 20 g/10 min produce viscosity mismatch in the extruder and visible parison chatter. HDPE-based masterbatches with a carrier melt flow below 1.0 g/10 min are preferred because they preserve melt strength and die swell. Liquid colourants should be evaluated for vapour generation at the die head; volatile carrier solvents above 0.2 wt% can create splay and loss of interlayer adhesion in coextruded structures.
The environmental stress-crack resistance of HDPE GM5010T2B does not remain constant through repeated processing. Virgin resin with an ESCR greater than 600 h under ASTM D1693 condition B may show a decline of 25–40% after three extrusion cycles when reprocessed without addition of a stabilization masterbatch. The loss is concentrated in the high-molecular-weight tail and is accelerated by exposure to iron and copper residues from worn screw and barrel surfaces. For applications requiring long-term containment of surfactants or petroleum-based fluids, internal regrind above 30 wt% should be qualified by ESCR testing on the finished container rather than by melt flow alone.
The grade is also incompatible with uncontrolled blending into low-molecular-weight injection moulding regrind streams. A bimodal melt viscosity distribution may produce localized parison thinning, weld-line flutter, and inconsistent pinch-off thickness even when the blended melt flow appears acceptable. If mixed with a 0.45 g/10 min injection grade at 15 wt%, the blend may display adequate average melt flow but insufficient melt strength for deep-draw moulds. The high-molecular-weight mode can be separated from the low-viscosity mode in accumulator heads during long hold periods, resulting in top-to-bottom wall-thickness variation exceeding 0.2 mm in containers with a 300 mm parison hang length.
When regrind exceeds 30 wt%, the blended feed melt flow rate is higher than virgin resin because regrind has undergone chain scission during previous extrusion. In shuttle blow moulding, this shift produces shorter parison hang time, thinner top-wall sections, and greater flash thickness at the pinch-off. The extrusion setpoint may be decreased by 5–10 °C to restore melt viscosity, but this reduction increases backpressure and may lower output by 8–15%. An alternative is to increase the virgin resin buffer ratio or to reduce the die gap from 1.2 mm to 0.8 mm while raising accumulator fill pressure. The exact compensation is machine-specific; published data for a single correction across all configurations is limited.
If the line is equipped with gravimetric hopper loaders, bulk density variation in regrind flakes creates feed rate fluctuations of 3–6% unless the loader is recalibrated. Mixing flake regrind with pelletized virgin resin without a static mixer can produce melt temperature heterogeneity of 5–10 °C at the die, visible as wavy parison edges or inconsistent container weight. For containers below 1 L, shot-to-shot weight variation should be maintained below 0.5 g; regrind flake geometry and bulk density then become more important than melt flow ratio.
The base HDPE olefin polymer falls within the scope of 21 CFR 177.1520 for olefin polymers intended for food contact when the density and solubility requirements of the finished article are met under the applicable use condition. The manufacturer’s lot-specific certificate of analysis should be used to confirm that the stabilizer package and any colour masterbatch comply with the intended food type and temperature. For European Union applications, compliance must be established under Regulation (EU) 10/2011 and its amendments, with overall migration testing using the simulants specified for the intended food-contact surface. Compliance for fatty foods with more than 8% alcohol or hot fill above 70 °C requires additional migration testing because polyolefins are permeable to nonpolar migrants.
The grade is subject to REACH registration under EC 1907/2006, and the supplier’s extended safety data sheet indicates the monomer residues and processing aids present. No RoHS restriction applies to the base resin; however, lead- or cadmium-based pigments used downstream are restricted under Directive 2011/65/EU. Users must validate that the finished article meets the specific overall migration limit of 10 mg/dm² for food contact under EU 10/2011 or the lower limit applicable to infant food. For UN-certified dangerous goods packaging, the resin itself does not confer certification; drop impact, hydraulic pressure, and stack-load performance must be demonstrated on the finished container according to the relevant UN Model Regulations test series.
Thermo-oxidative degradation of the material accelerates above 230 °C. Residence time in the accumulator head should be limited to 8–10 min at 200 °C to prevent yellowing, odour formation, and viscosity reduction. The grade should not be processed on low-torque single-screw extruders designed for 0.35 g/10 min resins without confirming drive capacity and screw cooling efficiency. Pre-drying is required when ambient relative humidity exceeds 60%; water concentrations above 0.02 wt% in the hopper may produce cosmetic defects in opaque containers. The material is not intended for high-pressure injection moulding of thin-wall parts below 1.5 mm wall thickness; the low melt flow limits flow length and requires higher clamp force than would be required for a 0.45 g/10 min injection grade. Published data for the specific injection moulding performance of this grade is limited, and moulding trials should be conducted before tooling release if conversion from injection moulding is under evaluation.
