Description

Poly(1-Butene) is a high-performance, semi-crystalline polyolefin polymer derived from the polymerization of 1-butene. This material is valued for its excellent creep resistance, high flexibility, and superior environmental stress crack resistance (ESCR) compared to other polyolefins. It serves as a critical component in the production of flexible packaging, piping systems, and as a modifier for other polymers across the global plastics and chemical manufacturing industries.

Application

• Piping Systems: Used in the manufacture of hot and cold water pressure pipes, offering excellent long-term hydrostatic strength and resistance to scaling.
• Flexible Packaging: Acts as a sealant layer in multilayer films for food and industrial packaging due to its low heat-seal initiation temperature and good hot tack.
• Polymer Modification: Employed as a compatibilizer and impact modifier to enhance the toughness and processability of polypropylene (PP) and polyethylene (PE) blends.
• Adhesives & Sealants: Serves as a base polymer for hot-melt adhesives, providing good adhesion to various substrates and flexibility.
• Consumer Goods: Used in the production of durable goods like housewares and storage containers where impact resistance is required.
• Wire & Cable: Applied as an insulation and jacketing material, leveraging its good electrical properties and moisture resistance.
