PTFE Fabric

Our PTFE fabric consists of a fiberglass substrate which is then coated with PTFE (polytetrafluoroethylene). This combination provides a superior non-stick surface and dimensional stability, allowing your equipment to work smoothly and more efficiently. These fabrics are designed for durability and long life at high temperatures, resulting in less production downtime. PTFE fabric withstands the high temperatures of heat sealing applications, while allowing the proper rate of heat transfer from the sealing unit to the package. It is also resistant to tears, punctures and abrasions. For these reasons, they are widely used on L-bar and table top impulse sealers.

Standard Grade PTFE Fabric

This series of PTFE coated fiberglass fabric was designed for use in the flexible packaging industry where excellent release, temperature resistance (500°F), durability and economy is required. Of course these products have found their way into many other applications such as: cooking sheets, gaskets and non stick, high temperature conveyor belting to name a few.
