Gasket

PTFE gaskets are one of the most suitable types of gaskets for a variety of sealing applications and are mostly based on virgin PTFE or filled PTFE. PTFE gaskets provide an extensive range of applicability.

PTFE is a fluoro polymer, which features an outstanding chemical resistivity to almost all chemicals, has good thermal insulation properties, and useful mechanical and processing characteristics. These PTFE features can be usefully applied in PTFE gaskets. They can be mostly used in valve seats, bearings, requested to resin sliding and chemicals, elastic bands for an-lubricated compressors, O-rings where elastomers can not withstand. An extended range of improved mechanical and processing properties can be additionally reached by a combination of virgin PTFE and different fillers.

Expanded PTFE Gaskets and Seal materials consist of virgin PTFE with multidirectional fibrous and/or porous structure, which the extruded PTFE consists of. A special manufacturing process provides the material with special chemical and physical properties. This can be of advantage in wide range of applications.

Advantages

Virgin PTFE, PTFE compounds and expanded PTFE offer a wide range of compounded products with good mechanical, electrical and thermal properties, chemical resistance, low friction coefficient and good resistance to wear.

Shape and construction size

Several types of PTFE gaskets are produced to meet the most demanding applications.
