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.

Delivery Options

Flange gaskets and sheets are available in thickness of 0,5mm, 0,8mm, 1mm, 1,5mm, 2mm, 3mm and 5mm. 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 E-drawing.

Temperature

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