Abstract

Reinforced easily moldable plastics are provided wherein particles of stretched porous polymer are incorporated into a plastic molding resin material to improve its physical properties without detracting from moldability. Particles or fragments of porous stretched forms of polyethylene, polypropylene, or polytetrafluoroethylene, are incorporated into a matrix of polytetrafluoroethylene polyvinylidene fluoride, or a copolymer of tetrafluoroethylene with perfluoroalkyl vinyl ether, hexafluoropropylene, ethylene, or trifluorochloroethylene.
