Only a few chemicals react with it. Its mechanical properties are low compared to other engineering plastics, but its properties remain at a useful level over a great temperature range — from -400 to 500°F (-240 to 260°C).
PTFE has excellent thermal and electrical insulation properties. And, it has a low coefficient of friction. It is difficult to make anything adhere to PTFE. A material may stick to it, but the material can be peeled off or rubbed off.
PTFE was the first fluorocarbon. It is the most chemically resistant plastic known. Mechanical properties can be improved by the addition of fillers such as glass fiber, carbon, graphite, molybdenum disulfide and bronze.
