This is a semi-crystalline polymer with high mechanical strength, thermal properties up to 240 °c, creep resistance under load, wear resistance and low coefficient of friction.

N.B. Its high temperature resistance is reduced by the addition of even limited load.

Product strengths:

·         Thermal stability beyond 240°c

·         Good chemical resistance

·         High dimensional stability

·         Good abrasion resistance and low friction coefficient

·         Very high rigidity also at low temperature

·         Electrically insulated

Product weakness:

·         Very high cost

·         No inherently UV stability

·         Relatively low notch impact resistance

·         Thermal resistance decreases  to as low as 140°c under pressure

·         Low resistance to acetone

Applications:

Mechanical: Heat resistance, dimensional stability at temperatures and high wear resistance make it a good choice for high performance pieces at low temperatures as well as high temperatures, e.g. gear bushes, in aircraft and aerospace industries.

Electrical: Very good dielectric and insulation properties.

Chemical: Used for valve seals, pump housings due to very good chemical resistance.

Nuclear: High resistance to Gamma radiation is particularly suited to nuclear applications.
