SHEETS MADE OF EXPANDED PTFE

CIMAFLON ePTFE sealing sheets

CIMAFLON gasket sheets are made of 100% pure virginal expanded PTFE (ePTFE). The special stretching process used in production creates a multidirectional fiber structure that gives the material special properties. PTFE (polytetrafluoroethylene) gaskets made from CIMAFLON gasket sheets exhibit only a minimal increase in width, extremely low creep and excellent adaptability to unevenness and damage to the sealing surfaces, even at high temperatures and surface pressures.

Possible applications

Gaskets made from CIMAFLON ePTFE gasket sheets can be used in almost all applications within the permissible temperature range thanks to their universal chemical resistance, high compressive strength and adaptability to the unevenness of the flanges.

They are used for sealing connections in the force main connection. The PTFE material is particularly suitable for applications with limited bolt force, large unevenness of the sealing surfaces and stress-sensitive components made of materials such as enamel, graphite, glass, GRP, aluminum, etc. In addition to sealing rings, CIMAFLON gasket sheets can also be used to punch complex and precise gasket shapes. Typical applications include gaskets for heat exchangers, agitator flanges, pipeline flanges and pressure vessels.
