Main Properties

Temperature Range

Virgin PTFE

Very low coefficient of friction and excellent chemical resistance.

-40°C to 260°C

15% and 25% Glass Filled PTFE

Decreased compressive strength and lower deformation under load than virgin PTFE. Better wear resistance, higher compressive strength and lower deformation under load.

-40°C to 260°C

5%,15% and 25% Carbon Filled PTFE

 Improved mechanical strength compared with virgin PTFE. Excellent wear properties, retains excellent frictional properties, good choice for seals and rings in dynamic and high-pressure applications

-40°C to 260°C

5% MoS2 Filled PTFE

Increased PTFE properties of hardness and wear resistance. Increased sliding properties and decrease friction.

-40°C to 260°C

Stainless Steel Filled PTFE

Extremely hard wearing. Excellent strength and stability under extreme loads and elevated temperatures.

-40°C to 260°C

TFM Series

Much denser polymer structure than Virgin PTFE. Displays better stress recovery.

-80°C to 260°C

PCTFE

Ideal sealing material for lower temperature and high pressure, good mechanical properties.
Excellent for LNG, Cryogenic and Oxygen use.

-240°C to 120°C

PEEK

Excellent chemical resistance and mechanical properties at elevated temperatures.

-40°C to 260°C

Carbon Filled PEEK

Many similar properties to Virgin PEEK. Particularly suitable for elevated temperatures and high load situations.

-40°C to 260°C

PFA

Excellent chemical and temperature resistance, electrical insulation properties

-100°C to +260°C

UHMWPE

Highly resistant to corrosive chemicals, with the exception of oxidising acids and organic solvents.

-60°C to +80°C

Acetal and Delrin

Good resistance to wear and deformation under load.

up to 80°C

PI (Polyimide)

Significantly higher modulus, excellent wear and friction properties, good thermal-oxidative stability and high mechanical strength

up to 320°C
