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.
