Gail HDPE G Lex B52A003

Gail HDPE G‑Lex B52A003 (and the related B52A003N) is a high‑density polyethylene (HDPE) blow‑moulding resin from GAIL (India) Limited developed for small‑ to medium‑size blow‑moulded containers. It is positioned for packaging that needs a dependable balance of stiffness, impact resistance, and environmental stress crack resistance (ESCR)—especially in applications where bottles are dropped, squeezed, stacked, or exposed to oils, detergents, and household/industrial chemicals.

GAIL describes this grade as having good processability with a medium melt flow index, enabling stable mould filling and cycle control for everyday container formats. Across the G‑Lex HDPE family, GAIL references CX slurry process technology as a platform associated with mechanical strength, impact performance, and ESCR.

For standards alignment, the datasheet notes conformance to natural‑resin designation IS 7328‑3B‑BB‑FXDA of IS 7328:2020 (polyethylene raw material for moulding/extrusion for blow‑moulded products). The resin is supplied as natural/white pellets, typically in 25 kg woven sacks, with standard storage guidance: keep material dry, store below 50 °C, and avoid contamination.

Technical insights

• Melt Flow Index (I2, 190 °C/2.16 kg): 0.42 g/10 min (typical): A medium MFI helps balance mould filling and parison control for blow moulding—supporting productivity without sacrificing container strength.
• Density (23 °C): 0.954 g/cm³ (typical): A density in this range supports stiffness and top‑load strength, which is important for stackable bottles and cans.
• Tensile strength at yield: 240 kg/cm² (typical): Indicates the resin’s ability to resist deformation under load—useful for bottles that must hold shape during handling and storage.
• Elongation at yield: 10% (typical): Suggests controlled ductility at yield; for blow‑moulded packaging, this helps balance stiffness with practical toughness.
• Flexural modulus: 10000 kg/cm² (typical): Higher modulus generally correlates with rigidity, helping containers feel firm and resist paneling.
• Izod impact strength: 120 J/m (typical): Supports drop resistance, especially relevant for edible‑oil and lube‑oil bottles that face rough handling.
• Shore D hardness: 62 (typical): Indicates surface hardness and scratch resistance—useful for consumer packaging aesthetics and handling.
• ESCR (10% Igepal): >500 hours (typical): A key selection factor for blow‑moulded containers; higher ESCR helps reduce cracking in contact with surfactants, oils, and stress‑concentrated areas (handles, corners, base).

Applications

Edible‑oil and ghee bottles (food packaging): B52A003 is positioned for edible‑oil and ghee containers where stiffness and drop resistance matter, and where packaging must hold shape during transport, stacking, and retail handling.

Lube‑oil and automotive fluid containers: For lube‑oil bottles and small jerrycans, ESCR and chemical resistance become critical. This grade is relevant where containers face long storage times, temperature changes, and exposure to oils and additives.

Toiletries and cosmetics bottles: In personal care packaging, converters need clean moulding, good stiffness, and impact resistance for daily‑use bottles. B52A003’s medium‑flow blow‑moulding positioning fits common toiletry formats.

Pharmaceutical and healthcare packaging (non‑sterile containers): The grade is referenced for pharma‑type bottles where consistent moulding and crack resistance are important. Final suitability depends on the specific product, regulatory requirements, and the converter’s compliance program.

Comparable alternatives

B52A003 is a purpose‑built blow‑moulding HDPE grade, so comparisons should be made against other container‑grade HDPEs—not pipe or film grades.

• B52A003N: Typically treated as the closest alternative within the same family. Substitution should be validated against the latest manufacturer documentation (and COA) to confirm any stabilizer/additive differences.
• General film or pipe grades (e.g., E52A003/E52A003N, P52A003): These are positioned for different processing methods and performance targets (film/pipe). Even if some base properties look similar, they are not direct substitutes for blow‑moulded container production without trials and datasheet matching.

Procurement takeaway: treat “equivalent grade” claims as unconfirmed unless you match (1) MFI, (2) density, (3) ESCR/impact targets, and (4) the manufacturer’s intended application class (blow‑moulded containers).
