WHY PTFE IS GREAT FOR SEALS
PTFE has many benefits making it ideal for sealing applications. Extremely high thermal stability, resistance to almost all chemicals, chemical inertness, Extremely low coefficient of friction (0.06), self lubricating properties, high melting point and the unique ability to resist thermal degradation.
PTFE is an ideal material for use in dynamic sealing applications, even when running dry as it does not suffer any stick/slip effect. This low friction characteristic also makes it the ideal choice for high speed dynamic applications as heat build up through friction is minimal. The addition of various fillers can alter some or all of these properties and can be adjusted to achieve desired physical properties to suit applications making our range of PTFE seals and materials extremely flexible
One of the main advantages of using PTFE for seals is the wide operating temperature range, –70 to +250 °C (–95 to +480 °F).
From wipers and piston seals through to rod and rotary, our experience and expertise are second to none.
