Production Description
PP copolymer blends exhibit improved impact strength at subzero temperatures (-20°C) through ethylene monomer incorporation. The material's low mold shrinkage (1-2%) and high flowability (MFI 35+) enable thin-wall molding applications. Recyclability (SPI code 5) supports circular economy initiatives.
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
