  • 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.
  1. Electrical & Electronics
  • Used in electrical enclosures, junction boxes, and cable reels due to its excellent insulation and mechanical properties.
  1. Furniture & Housewares
  • Applied in the manufacturing of chair shells, buckets, storage boxes, and fittings requiring strength and durability.

Secondary Uses

  1. Compounding & Blending
  • Acts as a base resin in masterbatch production, especially for impact-modified compounds and color concentrates.
  1. Construction Industry
  • Used in pipe fittings, panels, and mounting elements requiring light weight and impact strength.
  1. Stationery & Toys
  • Employed in making durable toys, folders, files, and toolkits due to its safety profile and moldability.
