| Polytetrafluoroethylene (PTFE) is a semi-crystalline fluoropolymer with an unusually high chemical and thermal resistance (-200 to +260°C, temporarily up to 300°C). In addition, this thermoplastic material has excellent sliding properties, a non-stick surface and the best insulating properties. This is in contrast, however, to low mechanical strength and a high specific gravity, comparable to other plastics. In order to improve the mechanical properties, PTFE can be used as a compound reinforced with additives such as glass fiber, carbon, or bronze. Due to its structure, this material is formed into semi-finished products using a compression process and machined afterwards with cutting/machining tools. — extremely high chemical resistance — very good temperature resistance (-200-+260°C, temporarily up to 300°C) — very low coefficient of friction (static friction = sliding friction) — extremely low surface tension (practically no materials stick to PTFE -> difficult to adhere to or weld) — high coefficient of thermal expansion — relatively low strength/rigidity — low dielectric constant — non-combustible |
