Leader Clipperlon 2130


Homogeneous expanded PTFE sheet, which uses product geometry rather than fillers or binders to address concerns associated with traditional PTFE material


Product Data Sheet


2130 is designed for oxidizing application, harsh chemical environments and areas where contamination is a problem. 2130 is completely chemically inert and is suitable for sealing all chemicals across the pH range with the exception of molten alkali metals and fluorine gas.


Clipperlon 2130 achieves very good stability and tightness with good blow-out resistance especially in demanding steel flange applications. The good resistance behaviour of the material leads to increased operating safety, even in changing operating conditions.

Chemical Compatiblity

Patricularly suitable for use with hydrofluoric acid, but not pure hydrogen fluoride. Best for use with string 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", 0,5mm, 1mm, 1,5mm, 2mm and 3mm. Other thicknesses available on request.. Standard gaskets can be supplied in accordance with ASME B16.21, EN12560-1 as well as EN1514-1. Non-standard or special gaskets can be manufactured according to customer drawings, or by given sizes or Edrawing.


Particularly suitable for temperature from – 240 ° up to 260 °C.
