PVDF – Polyvinylidene fluoride
High temperature plastic

Polyvinylidene fluoride (PVDF)is a fluoroplastic which can  be used even at a continuous operating temperature of up to 140°C. Advantages over other fluoroplastics are a good mechanical strength at a relatively low density.

Just like other fluoroplastics, PVDF is also very weather and UV-resistant. The material absorbs hardly any water and is very stable dimensionally. Due to its low  sliding friction coefficient, PVDF is also used in mechanical engineering as slide rail or also as guide rail and curve guidance. It is also often used in applications requiring high temperatures in the chemical industry.

PTFE – Polytetrafluoroethylene
High temperature plastic

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.

PEEK – Polyetheretherketone
High temperature plastic

Polyether ether ketone (PEEK) can be used at a continuous operating temperature of up to 260°C. This high temperature resistant, thermoplastic plastic has a high mechanical resistance. Even when subjected to high thermal loads, this material has very good sliding properties and has a high wear resistance. 

The extremely high chemical resistance in conjunction with  high dimensional stability makes PEEK a material that is mainly used for highly stressed components, such as scrapers, gears, valve flanges, curve rails and curve discs and plain bearings.  

PEEK can be easily machined.
