application:
1. Contact with highly corrosive media, sealing and gasket
materials of high-pressure systems, transparent materials for
observation windows, etc.
2. Electrical insulation materials, etc.
3. Low molecular weight PCTFE is used as sealing fluid, grease for
highly corrosive media and balancing fluid for navigation gyros.
