Gail HDPE G Lex B52A003N

Gail HDPE G‑Lex B52A003N is a UV‑stabilized high‑density polyethylene (HDPE) blow‑moulding grade from GAIL (India) Limited. It is positioned for small‑ to medium‑size containers up to about 5 litres, especially where buyers need a dependable balance of toughness, environmental stress‑cracking resistance (ESCR), and processability.

In practical packaging terms, B52A003N is selected for blow‑moulded bottles, cans and small jerrycans that must handle drop impact, longer shelf storage, and contact with oils, detergents, and cosmetic‑type formulations without premature cracking around high‑stress areas (base, handle, shoulder, neck). The “N” variant adds UV stabilization, supporting better handling and storage stability versus the non‑UV grade.

As per the manufacturer’s datasheet positioning, the grade conforms to natural‑resin designation IS 7328‑3B‑BB‑FXDA of IS 7328:2020 for polyethylene used in moulding/extrusion for blow‑moulded products.

Technical insights

• Melt Flow Index (I2) ~0.42 g/10 min (190°C/2.16 kg): A medium‑flow blow‑moulding MFI that supports stable parison formation and good processability for small‑to‑mid container sizes, while still maintaining stiffness and ESCR.
• Density ~0.954 g/cm³: Typical of HDPE grades designed for higher stiffness and strength—useful for bottles that must retain shape, stack well, and resist paneling.
• Tensile strength at yield ~240 kg/cm² & elongation at yield ~10%: Indicates a strength‑first profile with controlled ductility—helpful for dimensional stability while still resisting brittle failure.
• Flexural modulus ~10000 kg/cm²: Signals higher rigidity, supporting better top‑load performance and “firm” bottle feel.
• Izod impact strength ~120 J/m: Supports toughness for handling and drop events during packing, transport and use.
• Shore D hardness ~62: A balanced surface hardness for scuff resistance and handling without becoming overly brittle.
• ESCR (10% Igepal) >500 hours: A key decision metric for detergent, toiletry, lube‑oil and chemical‑adjacent packaging—helps reduce stress‑crack risk over time.
• Vicat softening point ~123°C: Useful for understanding heat resistance during storage/handling and for setting expectations in warm environments.

Applications

Edible‑oil and ghee bottles (up to ~5 L): B52A003N is commonly specified for HDPE edible‑oil packaging where manufacturers want a stiff, tough bottle with strong ESCR to reduce cracking at the base and shoulder during filling, capping, transport and shelf life.

Lube‑oil and automotive fluid containers: For lubricant packs, the combination of rigidity, impact strength and ESCR helps containers withstand handling abuse and long storage without stress‑cracking—especially important around handles and neck finishes.

Toiletries and cosmetics bottles: Toiletry and cosmetic formulations can be aggressive to plastics over time. This UV‑stabilized HDPE blow‑moulding grade is used when converters need consistent bottle performance, good stiffness and better resistance to formulation‑related stress cracking.

Pharmaceutical and healthcare packaging (non‑sterile bottles/containers): For pharma‑type bottles where robust handling, reliable mechanical performance and clean, consistent processing matter, B52A003N is positioned as a practical HDPE blow‑moulding option—subject to the converter’s compliance validation for the intended end use.

Comparable alternatives

• GAIL G‑Lex B52A003 (non‑UV): Closest internal alternative when UV stabilization is not required. B52A003N is typically preferred when storage/handling conditions call for added UV stability.
• Other HDPE blow‑moulding grades in India (similar class): Comparable products are generally evaluated by matching MFI (~0.42 range), density (~0.954), ESCR (>500 h), stiffness (flexural modulus), and impact. If any of these shift materially, converters may see changes in parison stability, cycle time, bottle rigidity, or stress‑crack performance.
• E52A003/E52A003N (not a direct equivalent): While sometimes discussed alongside B‑series grades in market summaries, equivalence should not be assumed unless your team matches the full TDS cluster and validates performance on your moulds and end‑use conditions.
