Blends of perfluoroelastomers and fluoroplastics

摘要

Cured articles are prepared from a composition that comprises a blend of a perfluoroelastomer and 51-300 phr of a semi-crystalline thermoplastic copolymer comprising copolymerized units of tetrafluoroethylene and 5-12 weight percent of a perfluoro(alkyl vinyl ether). The semi-crystalline copolymer is present as particles having an average particle size greater than 100 nm.
