Washington Penn Polypropylene Copolymer 20% Glass Reinforced, 11 MFI
Categories:	Polymer; Thermoplastic; Polypropylene (PP); Polypropylene with 20% Glass Fiber Filler
Material Notes:	Fiberglass & mineral-reinforced polypropylene compounds provide excellent tensile and impact properties. Mold shrinkage is similar to ABS and polystyrene. Compounds also have dimensional stability. The glass-reinforcement provides a better strength and modulus than any of the particulate mineral fillers.
