The semi-crystalline TFE (tetrafluoroethylene) is synthesized from the monomer TFE by polymerisation. The bond between carbon and fluorine is one of the strongest and most stable bonds in organic chemistry.
TFE is very well known under the name Teflon® (DuPont) and Hostaflon® (Dyneon).
Physical and Chemical Properties of Unfilled TFE
TFE and TFE compounds are reliable sealing materials with long livecycles and excellent chemical resitance.
To achieve the optimal functionality and system stability users must define the best combination of seal design, TFE compound and surface finished. Rely on our experts to help you find this combination.
Adding fillers to TFE can
This polymer maintains its excellent properties up to a temperature of 300°C
PEEK is for example used for guide rings and ballvalve seats, which must perform
to the highest standards.
PEEK is very well suited for applications at subzero temperatures down to -100°C.
The low specific weight of PEEK keeps the weight of PEEK components down.
The heat expansion ensures a small clearance
PEEK can replace metal because it combines great stability with an enormous weight advantage.
The unique properties of composite materials are used in applications with the highest safety, reliability and cost effectiveness requirements. In addition to the benefits they offer with regard to service life and operating costs (life cycle costs), composite materials also have the advantage of being lightweight!
These materials are based on carbon fibre materials bonded with PEEK.
Areas of application in which the operating temperature, operating pressure, compatibility of chemicals and the installation situation are particularly important.
We offer elastomers with individual and outstanding properties.
