Teflon™ PTFE 7A X by Chemours is polytetrafluoroethylene (PTFE) fluoropolymer grade. For big moldings like billets that need the best possible mechanical and electrical qualities, it is advised. It has a high bulk density, good dielectric characteristics, anti-stick surface, and moderate stiffness. It demonstrates great elongation, low friction, and chemical inertness. It offers resistance to corrosion, high temperatures, and fire. It can be treated by preforming and sintering and is temperature and frequency stable. Skived film and sheet, gaskets, packings, mechanical seals, shaft bearings, bridge or pipeline bearing pads, electrical insulators, piston rings, expansion bellows, diaphragms, and chemical linings all use Teflon™ PTFE 7A X. Meets the U.S. Environmental Protection Agency (EPA) 2010/15 PFOA regulations.
