This invention provides an elastomeric compressible mixture having the compressible properties of a rubber or rubber-like mixture with the heat characteristics of a conductive metal member. This compound material is made of two part polymerized tetrafluoro ethylene powder and the remainder about seventy five parts aluminum powder and twenty five parts silicone rubber. This mixture 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 mixture of material is used with heat and pressure to effect a seal of the heated thermoplastic film to an adjacent film.
