Utilized in industrial components like containers, crates, and pallets that require both toughness and structural integrity.

Ideal for consumer product packaging, including caps, closures, and rigid containers.

Electrical & Electronics
Used in electrical enclosures, junction boxes, and cable reels due to its excellent insulation and mechanical properties.

Furniture & Housewares
Applied in the manufacturing of chair shells, buckets, storage boxes, and fittings requiring strength and durability.

Secondary Uses

Compounding & Blending
Acts as a base resin in masterbatch production, especially for impact-modified compounds and color concentrates.

Construction Industry
Used in pipe fittings, panels, and mounting elements requiring light weight and impact strength.

Stationery & Toys
Employed in making durable toys, folders, files, and toolkits due to its safety profile and moldability.
