Blends of fluoroplastics and fluoroelastomers.

摘要

A composition and method for preparing it is disclosed. The composition is a blend of a cured fluoroelastomer which except for the cure sites is a perfluorocarbon and a thermoplastic copolymer of tetrafluoroethylene which is present as generally spherical particles having a particle size of less than l0 microns. The composition is prepared by blending the fluoroelastomer and thermoplastic copolymer at a temperature above the melting point of the thermoplastic copolymer followed by curing the fluoroelastomer.
