适用于高温应用的含氟弹性体组成物;FLUORINE-CONTAINING ELASTOMER COMPOSITIONS SUITABLE FOR HIGH TEMPERATURE APPLICATIONS

摘要

本发明描述一种可固化含氟弹性体组成物，其包括包含四氟乙烯、第一全氟烷基乙烯基醚及至少一种具有至少一个固化位点之第一固化位点单体的第一可固化全氟聚合物，其中四氟乙烯以至少约50莫耳%之量存在于该第一可固化全氟聚合物中；包含四氟乙烯、第二全氟烷基乙烯基醚及至少一种具有至少一个固化位点之第二固化位点单体的第二可固化全氟聚合物，其中该第二可固化全氟聚合物中包含氟塑胶粒子；及至少一种固化剂。本发明亦揭示固化组成物及由此类组成物形成之模制物件。; a second curable perfluoropolymer comprising tetrafluoroethylene, a second perfluoroalkylvinyl ether and at least one second cure site monomer having at least one cure site, wherein the second curable perfluoropolymer comprises fluoroplastic particles therein; and at least one curative. Cured compositions and molded articles formed from such compositions are also disclosed.
