WebPolytetrafluoroethylene (PTFE) is a highly crystalline polymer which is very resistant to attack by corrosives and solvents. It also has extremely good thermal resistance at temperatures up to 250C. Polytetrafluoroethylene is used in a broad range of applications, including gasketing, pump parts, bearings, and anti-stick applications.
