Description

Modified PTFE gasket material containing biaxial orientated chains to obtain a tight seal for demanding applications. Clipperlon 2120 is a very dense material with low compressibility, high recovery and low creep properties. Off-white in color and produced with Modified PTFE and barium sulfate filler. Clipperlon 2120 particularly suitable for use with hydrofluoric acid and chlorine applications and a wide variety of different media across the whole pH-range. Due to the high density this material is highly recommended for applications with monomers to avoid the ‘popcorning’ effect. This effect will be result when the monomer enters the micro-voids of the PTFE.

Available also for Heat Exchanger applications.

Chemical Compatiblity

Particularly suitable for use with hydrofluoric acid, but not pure hydrogen fluoride. Best for use with strong alkalis, solvents, fuels, water, steam and chlorine. Other applications include solvents, fuels, water, oil, chlorine and caustics. A chemical resistance listis available upon request.

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.

Temperature

Temperature from -450 ºF up to 500 ºF.
