| 说明书摘要 | 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, the weight percentage of the former is 0.1-99.9% and the latter is 99.9-0.1% respectively. The processes for preparing the fluoropolymer alloys are 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 articles show a great improvement in creep property and also a prolonged service life in comparison with those made from ordinary polytetrafluoroethylene. | ||
