Abstract

See full text

A process for producing unmelted fibrous polytetrafluoroethylene (PTFE) resin from which multi-directional planar oriented structures such as sheets and planar shapes can be readily fabricated. Unfilled forms as well as filled and reinforced products are achievable. Novel composite-plied structures or unsintered sheets can be built by layering two (2) or more sheets containing functional fillers or reinforcements and then sintering said layers to provide a homogenous bond between all layered sheets. True reinforcement of formed fluoropolymer structures can be produced with tensile properties, which exceed the strength of virgin products. Microporous asymmetric membranes, which have decreasing pore size in a series of plies can be readily fabricated.
