The material PTFE, with the trade name Teflon®, is a semi-crystalline fluoropolymer with many unique properties. PTFE has an unusually high thermal stability, -200 to +260°C, short-term up to 300°C, chemical resistance and an equally high melting point. At the same time, PTFE products have excellent sliding properties, excellent electrical resistance and a non-stick surface. However, in contrast to these properties it has low mechanical strength and high specific weight compared to other plastics. To improve mechanical properties, PTFE plastics can be reinforced with additives such as glass fibers, carbon or bronze. Due to its structure, PTFE is often shaped into semi-finished products by compression and then machined with cutting/machining tools.
