ABSTRACT:
Improved material and method for use in sealing plate and frame apparatus, such as a plate and frame heat exchanger, are provided. The gasket material comprises a core of elongated polytetrafluoroethylene (PTFE) contained within a tight wrap of high strength film. The gasket material has the exceptional operational properties of PTFE, while being resistant to cold flow or "creep" which distorts most PTFE seals under heavy unconfined compression. The preferred material is pre-compressed to aid in installation.
