Polytetrafluoroethylene (PTFE) – TECAFLON PTFE is a natural – semi-crystalline fluoropolymer with an unusually high chemical and thermal resistance (-200 – + 260 ° C, temporarily 300 ° C). In addition, this thermoplastic material has excellent shear properties, a non-stick surface and best insulating properties. However, compared to other plastics, it is in contrast with low mechanical strength and a high specific gravity. PTFE can be used as a compound reinforced with additives such as glass fiber, carbon or bronze to improve mechanical properties. Due to its structure, this material is formed into semi-finished products by a compression process and then processed with cutting / machining tools.
