ePTFE Sealing tape with self adhesive
CIMAKAFLON the self adhesive PTFE gasket tapes consist of 100% pure virgin expanded ePTFE. The special stretching process used in manufacturing products a multi-directional fibrous structure, giving the gasket material specific characteristics and properties. CIMAKAFLON ePTFE flat gasket tapes are also at higher temperatures and surface pressure, similar to our ePTFE gasket sheets, show nearly no increase in width, have an extremely low creep and feature an exceptional adaptability to unevenness and damages on the flange surface.
Advantages and applications
ePTFE gasket tapes are suited for sealing in frictional connection, for large flange diameters and geometrically complicated surfaces. Within the admissible temperature range they are used for sealing steel flange components, as well as components with stress-sensitive materials like enamel, glass, ceramic, GRP. Typical applications are the densities of large pressure vessels, Tube bundle- and block heat exchangers, mixers, apparatus, etc. ePTFE flat gasket tapes are used in the chemical industry general, in power plants, in the food industry, pharmaceutical applications, in plant engineering, etc.
ePTFE gasket tapes offer a wide range of benefits like:
- no punching required
- fast installation
- no wast or scrap
- excellent adaptability to uneven sealing surfaces
- almost no increase in width under stress (thus suitable also for narrow flange surfaces)
