PTFE + 25 % glass fibre

A linear-chain polymer of great molecular length. Its structure, made of long carbon chains saturated with fluorine, gives it chemical, mechanical, electrical and thermal properties that meet the most demanding industrial requirements.

This is a glass-fibre-filled PTFE. It has high chemical resistance, except to alkalis and hydrofluoric acid, and high resistance to wear and friction.

Main characteristics

• Improves compressive strength and wear resistance.
• Improves the friction resistance of PTFE at high and low temperatures.
• Excellent chemical stability, except with strong alkalis and hydrofluoric acid.
• Better thermal conductivity and coefficient of friction when combined with molybdenum disulphide or graphite.
• Excellent electrical properties.

Typical uses

The most common filler for seals with rotary and reciprocating movements: pneumatic and hydraulic applications, bearings, piston rings, valve seats and moving mechanical parts.
