Outstanding properties of fluorocarbon polymers (or fluoroplastics) include inertness to most chemicals and resistance to high temperatures. Fluoroplastics have a rather waxy feel, extremely low coefficients of friction, and excellent dielectric properties that are relatively insensitive to temperature and power frequency.
PTFE – polytetrafluoroethylene is extremely heat-resistant and has outstanding chemical resistance, being inert to most chemicals. Its coefficient of friction is lower than that of any other plastic, and it can be used unlubricated.
PVDF – polyvinylidene is a tough fluoroplastic with high chemical resistance and weatherability. It is self-extinguishing and has a high dielectric loss factor. A melt-processible plastic material, it is used in seals and gaskets for chemical process equipment and in electrical insulation.
