Abstract
Disclosed herein is a method to produce a semi-crystalline fluoro-polymer film. A semi-crystalline fluoro-polymer material is used. The material is compressed to produce the film. During compression, the material is maintained at a temperature below the melting point of the material. The compression step can be cycled to allow cooling of the material between compression stages. Alternative methods are provided for compressing the material with a co-extrusion substrate, extruding the material and utilizing mandrel expansion for the material.
