Aromatic Polyester-Filled PTFE

Aromatic Polyester is resistant to high temperatures. Aromatic Polyester is slightly hydrophilic, so it is preferable to use the material in dry environments.

Aromatic polyester filled PTFE materials exhibit excellent wear resistance, and their non-abrasive nature prevents the galling of soft mating surfaces. 

Aromatic polyester filled PTFE materials are used in seal components for both static and dynamic applications.
