Gail HDPE G Lene I50A180

G‑Lene I50A180 is a high‑density polyethylene (HDPE) injection‑moulding grade from GAIL (India) Limited, designed for fast filling of thin‑wall household parts where surface finish and cycle time matter. In GAIL’s own technical sheet, the grade is positioned for household products such as buckets, mugs, and similar injection‑moulded items, highlighting excellent processability, low degree of warpage, and superior gloss.

As a very‑high‑flow HDPE (high MFI) with high density, I50A180 is typically selected by moulders who want a practical stiffness–toughness balance for everyday domestic containers and general rigid moulded goods—especially when the mould has thin sections, long flow lengths, or needs consistent appearance across high‑volume production runs. GAIL states the resin conforms to the natural‑resin designation IS 7328‑3B‑MB‑FXDE of IS 7328:2020 (certificate available on request), which is highly relevant for moulded household product applications in India.

Technical insights (what the key properties indicate)

Flow & mould filling (MFI)

With a typical Melt Flow Index (190°C/2.16 kg) of 20 g/10 min, I50A180 sits in the very‑high‑flow injection moulding class. Practically, this supports faster filling, easier processing of thin walls, and shorter cycle times—helpful for buckets, mugs, and toy parts where productivity and finish are critical.

Stiffness & part rigidity (density and flexural modulus)

A typical density of 0.952 g/cm³ indicates a higher‑density HDPE structure that generally contributes to stiffness and dimensional stability. A flexural modulus around 9000 kg/cm² (as commonly mirrored by distributor listings) aligns with the “houseware rigidity” requirement—parts feel firm and hold shape under normal household loads.

Strength & ductility (tensile and elongation)

Typical tensile strength at yield is 230 kg/cm² with elongation at yield of 10%, and elongation at break of 400% (on compression‑moulded specimens). This combination is commonly read by moulders as “stiff enough to hold form, but not brittle,” supporting everyday handling and drops typical in domestic use.

Stress crack resistance (ESCR)

The ESCR value is listed as <10 hours (10% Igepal, ASTM D1693, F50), which signals that this is not a stress‑crack‑resistant packaging/industrial container grade. It’s better positioned as a standard household injection grade where high flow, gloss, and warpage control are prioritized over long‑term ESCR performance.

Heat performance (Vicat)

A typical Vicat softening point of 122°C helps buyers assess heat tolerance for household environments (warm water exposure, general heat near kitchens, etc.), without positioning it as a high‑temperature engineering plastic.

Processing guidance (from the datasheet)

GAIL’s processing guidance lists barrel temperature 200–280°C and mould temperature 25–40°C—useful guardrails for stable moulding, finish control, and warpage management in thin‑wall parts.

Applications (industries & use cases)

Household containers and utility items: I50A180 is commonly specified for injection‑moulded buckets, mugs, and household containers where thin walls, good surface gloss, and low warpage are important. The very‑high‑flow nature supports clean filling and consistent appearance in high‑cavity or fast‑cycle production.

Toys and general rigid moulded goods: For toy components and general‑purpose rigid injection parts, moulders often need a balance of stiffness, ductility, and processability. I50A180’s typical tensile/elongation profile and high flow make it suitable where the part geometry is complex or thin, and where visual finish matters.

Thin‑wall injection moulding for mass production: When the priority is productivity—short cycle times, reliable filling, and stable dimensions—very‑high‑flow HDPE grades like I50A180 are often preferred over lower‑MFI options that may offer different mechanical emphasis but can be slower to fill in thin sections.

Comparable alternatives (positioning vs similar grades)

GAIL I56A200U (similar flow class): I56A200U is often referenced as a comparable GAIL injection grade with similar high flow (commonly cited around 20 MFI) and slightly higher density positioning in some listings. Where confirmed by manufacturer sheets, moulders may compare these two for gloss/warpage behaviour and the stiffness “feel” of finished parts. Do not assume drop‑in equivalence unless the latest GAIL TDS values and IS designation match your requirement.

GAIL I50A250 (higher flow): I50A250 is positioned as a higher‑flow option (commonly cited around 25 MFI). In general, higher flow can further improve thin‑wall filling and cycle time, but may shift the balance of mechanical performance depending on the exact grade design. Use manufacturer TDS comparison to validate performance targets (warpage, stiffness, impact).

Lower‑MFI injection grades (e.g., crate/rigid emphasis): Compared with lower‑MFI HDPE injection grades, I50A180 is clearly positioned for thin‑wall houseware productivity and appearance (gloss, warpage control). If your application needs higher ESCR or different long‑term performance, a different HDPE family/grade selection may be more appropriate.
