Production Description
PP (polypropene), a high-performance polyolefin thermoplastic, is synthesized via chain-growth polymerization of propylene monomers. Distinguished by its semi-crystalline structure and non-polar nature, this rugged white material outperforms polyethylene in heat tolerance and surface hardness while maintaining exceptional chemical resistance.
Key Advantages Over Standard PP
Tailored performance for niche applications.
Cost-effective alternative to engineering plastics like ABS or nylon.
Retains PP’s inherent benefits (lightweight, chemical resistance) while addressing weaknesses.
