ABSTRACT:
A composite material is presented comprised of a ceramic filled fluoropolymer wherein the ceramic is coated with a silane and the ceramic has a volume % fraction of between about 26-45. The composite of this invention exhibits excellent chemical resistance, particularly to alkaline environments. Preferably, the silane comprises a blend of at least one phenyl silane and at least one fluorosilane. The silane is preferably coated to a level of 10% of the total weight of ceramic filler.
