Gail HDPE G Lene I50A250

Gail HDPE G‑Lene I50A250 is a high‑density polyethylene (HDPE) injection‑moulding grade from GAIL (India) Limited under the G‑Lene polymer range. It is positioned as a very‑high‑flow resin designed for medium‑to‑large household moulded parts where fast filling, good surface finish, and dimensional stability matter—such as buckets, flowerpots, and toys.

From a polymer‑engineering standpoint, HDPE is a linear polyolefin known for a strong stiffness‑to‑weight profile and practical impact resistance for everyday domestic products. In I50A250, the high flow supports easier mould filling for larger sections and complex geometries, while the grade is described as offering excellent processability, high gloss and flow, good mechanical properties, and a low degree of warpage—useful for moulders trying to balance cycle time, appearance, and part stability.

For buyers who need standards alignment for household moulded products, GAIL states the grade conforms to natural‑resin designation IS 7328‑3B‑MB‑FXDE of IS 7328:2020 (certificate available on request). This makes I50A250 a relevant option when procurement teams are filtering HDPE injection grades by Indian standard designation in addition to flow and density.

Technical insights

Typical datasheet‑style properties (from the provided manufacturer/brochure references)

• Melt Flow Index (MFI, I2; 190°C/2.16 kg): 25 g/10 min (ASTM D1238)
• Density (23°C): 952 g/cm³ (ASTM D1505)

What these properties indicate for performance

MFI (flow) — why it matters: A typical 25 MFI places I50A250 in the very‑high‑flow HDPE injection‑moulding class. Practically, this can help with faster cavity fill, easier gating, and shorter cycle times on medium‑to‑large parts (where thick sections and long flow lengths can otherwise slow production).

Density — what it signals: A density around 0.952 g/cm³ is characteristic of HDPE grades built for stiffness and shape retention versus LDPE/LLDPE. For household containers and utility parts, this supports a more rigid feel and better dimensional control.

Mechanical properties note (important): The provided excerpt does not include a full mechanical table (tensile, elongation, flexural modulus, etc.). For engineering sign‑off, confirm these values from the official GAIL datasheet or a distributor certificate before final material selection.

Applications

Buckets and utility containers (houseware)

For HDPE bucket moulding and similar utility containers, I50A250 is selected when moulders want very high flow to fill larger sections quickly while still maintaining the stiffness expected from HDPE. The grade’s positioning around low warpage and good surface finish supports consistent part appearance across high‑volume production.

Flowerpots and medium‑to‑large household items

In flowerpot moulding HDPE applications, flow and gloss are often prioritized because parts are large, visible, and commonly produced in multiple colours. I50A250’s high‑flow profile can help reduce fill‑related defects and improve productivity for medium‑to‑large moulds.

Toys and general injection‑moulded components

For toy parts and general household injection moulding, the combination of HDPE stiffness with high flow can be useful for producing parts with good aesthetics and stable dimensions. As the grade is not described as UV‑stabilized in the provided inputs, outdoor exposure requirements should be evaluated case‑by‑case.

Comparable alternatives

Within GAIL’s own G‑Lene portfolio, I50A250 is commonly positioned alongside I50A180 and I56A200U as household‑focused injection grades.

• G‑Lene I50A180: Typically referenced at ~20 MFI with similar density (~0.952 g/cm³). Compared to I50A180, I50A250’s higher MFI (25) is positioned for easier flow and faster filling, especially helpful for medium‑to‑large The trade‑off in many polymer families is that higher flow can come with reduced toughness or ESCR versus lower‑flow counterparts—so confirm with official mechanical/ESCR data for your specific part.
• G‑Lene I56A200U: Also referenced around ~20 MFI, and described as UV‑stabilized in the provided inputs. If your application needs better outdoor durability, I56A200U may be considered; if your priority is maximum flow for large moulds, I50A250 is positioned as the higher‑flow choice.

Across the broader Indian market, other HDPE injection‑moulding grades exist with similar flow/density bands, but direct equivalence is not confirmed unless the manufacturer datasheets match on MFI, density, mechanicals, and the relevant IS designation.
