  • Fluoropolymer alloys
    Patent number: 5087680
    Abstract: This invention relates to fluoropolymer alloys made of melt fabricatable extra-high-molecular weight fluorinated ethylene-propylene copolymer (EHMW-FEP) and one or more other polymers. In fluoropolymer alloys made of EHMW-FEP and polytetrafluoroethylene, weight percentage of the former is 0.1-99.9% and the latter is 99.9-0.1%. The processes for preparing fluoropolymer alloys are blend of dried powder co-mill or wetted powder co-mill. Using the fluoropolymer alloys of this invention, various kinds of articles have been fabricated by melt compression or cold compaction and sintering. These properly fabricated articles show a great improvement in creep property and also a prolonged service life in comparison with those made from ordinary polytetrafluoroethylene.
