Polyetrafluoroethylene (PTFE) was the first fluorocarbon.
It is a semi-crystalline high-performance thermoplastic that is the most chemically resistant plastic available. Only a few chemicals react with it. Its mechanical properties are low compared to other engineering plastics, but its properties remain at a consistent level over a great temperature range; from minus 400 degrees F/-240 degrees C to 500 degrees C/260 degrees C.
Mechanical properties can be improved by the addition of fillers such as glass fiber, carbon, graphite, molybdenum disulfide and bronze. PTFE has excellent thermal and electrical insulation properties. It has a low coefficient of friction, making it difficult to make anything adhere here to PTFE.
Available in sheet(1/16” to 2” thickness), rod 1/8” to 2” diameter and tubing.
