ABSTRACT:
An improvement in a process for preparing a laminate consisting of a fluorocarbon copolymer sheet of 5 or more mill thickness and a fabric is disclosed. The improvement is using a thin sheet of a fluorocarbon copolymer having a specific melt viscosity low enough to enable the copolymer to wet and penetrate the fabric at fabrication temperatures as an interlayer between the fabric and thick fluorocarbon copolymer sheet and then integrally bonding the laminate by means of heat and pressure. The use of the interlayer increases the level of adhesion between the thick sheet and the fabric.
