PTFE gasket - W207

W207 PTFE Gaskets
PTFE gaskets are one of the most suitable types of gaskets for a variety of sealing applications and are mostly based on virgin PTFE, PTFE compounds, filled PTFE or expanded PTFE. And what provides the PTFE gaskets with such an extensive range of applicability? The answer is PTFE. PTFE is a fluoropolymere, which features an outstanding chemical resistivity to almost all chemicals, good thermal insulation properties, and useful mechanical and processing characteristics. The above-mentioned 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 the applications.
Advantages:
Virgin PTFE, PTFE compounds and expanded PTFE offer a wide range of compounded products with good mechanical properties, electrical properties, thermal properties, chemical resistance, low friction coefficient and good resistance to wear.
Shape and construction:
Several types of PTFE gaskets are produced to meet the most demanding applications.
