Description

Modified PTFE sheet manufactured with biaxial oriented longer molecule chains specially designed for high demanding applications. Due to this specific material structure and special manufacturing process a low creep properties are achieved. Fawn in color and produced with Modified PTFE and Solid Silica Beads as a filler.

Available also for Heat Exchanger applications.

Product Data Sheet

Application

A general purpose gasket material for sealing applications across the whole pH-range, reduced creep, and good sealability at low stress.

Advtantages

Clipperlon 2100 has a very good cold flow resistance and good stress retention properties, even at elevated termperatures. Because of the low diffusion properties and uniform structure, Clipperlon 2100 is the ideal sealing material for applications with the highest demands for low emissions.

Chemical Compatiblity

Particularly suitable for use with strong acids (except hydrofluoric acid) and alkalis. Other applications include solvents, fuels, water, steam and chlorine. A chemical resistance list available upon request. Pressure up to 1200 psi. Temperature from -450 °F up to 500 °F.

Delivery Options

Flange gaskets and sheets are available in thickness of 1/32",1/16", 1/8". Other thicknesses available on request. Standard gaskets can be supplied in accordance with ASME B16.21. Non-standard or special gaskets can be manufactured according to customer drawings, or by given sizes or Edrawing.
