PTFE Gasket Material

PTFE Sheet The material offers the tightest sealing solution which can be used for the entire pH range and can be used with high temperature as well as cryogenic applications. Sheets are easy to cut into specific requirements.

Virgin PTFE Sheet Gasketing Manufactured from PTFE this sheet is ideal for a wide range of gasketing applications.

Food, and Chemical applications are often sealed using PTFE.

The first thing that must be determined is what type of PTFE gasket material your looking for. The first and most common form is a virgin PTFE gasket material. Virgin PTFE is specified for medical or electrical applications. Most applications however, are not medical or electrical and can easily be satisfied with mechanical grade PTFE.

Mechanical grade PTFE is almost identical to Virgin and to the naked eye is very hard to differentiate. A very small percentage of reprocessed PTFE has been added to Virgin PTFE to produce mechanical grade. The percentage will very by manufacturer.

Other grades of PTFE include filled PTFE (which can be filled with a wide range of materials all producing various desired results including wear resistance, cold flow resistance and conductivity). The Filler materials commonly include, Silica, Glass beads, Barium Sulfate, Carbon/Graphite or assorted metals. The mthod of production also varies providing various techical characteristics.
