Product portfolio by PTFE Compounds Germany GmbH

The outstanding properties of Polytetrafluorethylen (PTFE) create a superiority in thermal properties compared to all other plastics and fluorine plastics. The maximum continuous operating temperatures range is defined from -200 °C up to + 260 °C.

 

PTFE

 

The almost universal chemical resistance of PTFE has made it a highly favoured material for sealing applications. Only reducing agents such as alkali metals (sodium, potassium, etc.) and elemental fluorine and fluorine compounds have an impact on PTFE.

 

Another advantage of PTFE products is the excellent insulating properties. In addition hereon, the material has a very low coefficient of friction. Please click the product group in order to find detailed information on our product portfolio.

Modified PTFE

 

By usage of the modifier Perfluorpropylether (PPVE) a modification of PTFE is achieved. Modified PTFE is characterized by a reduced cold flow and a lower deformation under load.

 

It has fewer pores compared to regular PTFE as well as a lower permeation. Furthermore, mechanical properties such as yield stress, elongation and stiffness at high temperatures are improved.

 


Compounds on the basis of modified PTFE and PTFE

 

A PTFE-compound is a physical mixture of PTFE or modified PTFE with fillers of various kinds. By specific admixing of fillers, characteristics of the material can be improved. Hereby, customized compounds perfectly fitting to every single application are created.

 

Improvement areas are for instance:

 

                 Pressure resistance

                 Abrasion

                 Thermal conductivity

                 Reduction of the coefficient of thermal expansion

 

Please note that when selecting filler-materials for compounds, it is necessary to review the chemical resistance case by case basing on the application.
