REINFORCED PTFE

VIRGIN PTFE

PRODUCT DESCRIPTION:

A reinforced PTFE material that has a low coefficient of friction, high creep resistance, high load bearing capacity and high wear resistance. Specifically developed for slide bearing and skidway applications.

A PTFE material that has a low coefficient of friction and high chemical inertness. Suitable for a very wide range of applications that require these characteristics.
