PB10000 SERIES

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.
