Long Glass Fiber Reinforced Polypropylene

OnForce™ Long Glass Fiber Reinforced Polypropylene Composites

Add Strength Without Weight

OnForce™ long glass fiber reinforced polypropylene composites provide extremely high stiffness and good impact resistance for metal replacement and other structural applications where high strength-to-weight ratio is key.

Long fiber technology boosts resistance to creep and fatigue as well as dimensional stability while maintaining exceptional surface finish when compared to standard short-fiber products.

When impact strength, elastic modulus and material strength are required, OnForce formulations offer a reliable solution for demanding applications in transportation, industrial and outdoor markets.
