ABSTRACT:
This invention provides an elastomeric compressible mixture having the compressible properties of a rubber or rubber-like compound with the heat characteristics of a conductive metal member. This compound material is made of two parts tetrafluoro ethylene powder and the remainder about seventy-five parts of heat-conductive metal powder such as aluminum powder and twenty-five parts silicone rubber. This compound is attached as a flat sheet to a conductive metal backup member or may be a cover for a conductive metal roll. This mixture is used to accommodate irregular thicknesses of thermoplastic films. This elastomeric mixture as a material is used with heat and pressure to effect a seal of the heated thermoplastic film to an adjacent film.
