Production Description
PP exhibits semi-crystalline behavior with high-impact resilience, structural integrity, and organic/acid-base resistance. Applied across industries including Australian coin manufacturing. Optimized via glass fibers (30% yields 0.7% shrinkage), metal additives, or rubber modifications. MFR 1-40 inversely links impact tolerance to tensile strength, copolymers outperforming homopolymers. Despite 1.8-2.5% crystalline shrinkage, directional consistency exceeds HDPE standards.
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
