Polytetrafluoroethylene (PTFE), commonly known as “the king of plastics”, is a polymer compound formed by the polymerization of tetrafluoroethylene. Insulation and good resistance to aging. Used as engineering plastics, can be made into PTFE tube, rod, tape, plate, film, etc. Generally used in corrosion-resistant pipes, containers, pumps, valves, radars, high-frequency communication equipment, and radio equipment with high performance requirements.
It is made of PTFE resin as the main base material and combined with high temperature resistant resin. It needs high temperature baking to form a film.
