Engineering Grade Modified PP Glass Fiber Reinforced For Injection Molding Solution

Engineering-Grade Modified PP with Recycled Glass Fiber – Injection Molding Solution

Product models in the automotive lighting field

Production Description

Polypropylene (PP), a semi-crystalline thermoplastic, exhibits exceptional impact resistance, robust mechanical strength, and chemical stability against organic solvents/acid-base corrosion. Widely utilized in industrial applications and even Australian currency production. PP modification typically involves glass fibers (30% content reduces shrinkage to 0.7%), metal additives, or thermoplastic rubbers. MFR ranges 1-40 inversely correlate impact resistance with tensile strength, while copolymer variants outperform homopolymers at equal MFR. Crystalline structure causes 1.8-2.5% shrinkage rates, yet demonstrates superior directional uniformity versus HDPE.

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
