Glass Fiber Reinforced Recycled PP: High-Performance Engineering Plastic for Injection

Product models in the automotive lighting field

Production Description

PP's semi-crystalline nature yields high-impact durability, mechanical integrity, and organic/acid-base resistance. Essential in industrial contexts and Australian monetary systems. Modified using glass fibers (30% reduces shrinkage to 0.7%), metal particles, or rubber polymers. Lower MFR (1-40 range) prioritizes impact resistance over tensile strength, with copolymers outperforming homopolymers. Crystallization-induced shrinkage (1.8-2.5%) maintains better directional stability than HDPE materials.

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
