High Impact Modified Polypropylene Injection Grade Glass Reinforced Polypropylene

Modified Polypropylene PP with Recycled Glass Fibers – Injection-Grade Engineering Plastic

Product models in the automotive lighting field

Production Description

PP homopolymer - synthesized through coordination polymerization - exhibits flexural modulus up to 1.7 GPa and Rockwell hardness R80-110. The material's narrow molecular weight distribution enables high-clarity applications when nucleated, while copolymer variants improve low-temperature impact strength.

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.

Product application in LED light field



Product application in Switch and Socket



Product application in Toilet-Seat
