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
