Polytetrafluoroethylene (PTFE)is a thermoplastic, high temperature plastic, which is non-combustible and has a high thermal resistance. The application area extends from -200°C to +260°C. For a short time, even an application of up to nearly 300 °C is possible. However, the material is subjected to a relatively high thermal expansion.
Belonging to the group of fluoroplastics, PTFE has an extremely high resistance to chemicals and high sliding properties. However, with its high specific weight and a relatively low resistance and hardness, the applications are limited.
The material is well machinable, but due to the surface texture it is hard to bond or weld.
PTFE is especially used in areas with high operating temperatures and when in direct contact with chemical media. For the area of mechanical engineering, the chemical industry or even for other areas, PTFE is machined as insulators, seals, pump parts or stamps.
