Superior Stiffness and Strength


Washington Penn Plastic modular glass fiber technology is a polypropylene material platform that provides superior stiffness and strength for physically robust injection molding applications.  Our modular technology offers up to 25% increased tensile strength and up to 10% increased flexural modulus, compared to traditional glass fiber reinforced PP compounds.

The improved physical performance of these materials offers new opportunities to replace more expensive engineered resins, while often matching existing mold shrinkage and providing weight savings.
