Abstract
A multilayer compression packing seal having a fluoropolymeric layer of a multiphase composition of a continuous phase of thermoplastic polymer material with a dispersed fluoroelastomeric amorphous phase provides a basis for improved static seals in assemblies. In one form, the seal is treated with radiation. The fluoropolymeric layer is remarkably thin while demonstrating excellent permeability resistance to fuels and amine bases.
