Application area

Engine parts, plain bearings, insulations, butterfly valves

Product specification

Heavy-duty plastic

Outstanding mechanical stability, stiffness and hardness

High heat stability

Good impact toughness

Best wear resistance

Very good chemical resistance, except for conc. sulfuric acid, conc. nitric acid and aqua regia (chloronitrous acid)

Outstanding hydrolysis resistance

Very high temperature resistance (outstandingly high operating temperature)

Good creep resistance even at high temperatures

Very high dimensional stability

Inherent flame resistance

Low formation of smoke

Good electrical insulating properties as well as favorable dielectric characteristics

Outstanding radiation resistance

High-quality technical plastic (high-tech polymer), predominantly for mechanically and thermally highly loaded parts, also with antifrictional property for machine building, pump and fitting construction as well as for electrical engineering.

For replacement of PTFE because of increased mechanical stability, outstanding wear resistance.

For replacement of metals for pump bottom parts, valve seats, sliding elements, gearwheels, carrying wheels, high-temperature insulating parts in electrical engineering, parts in touch with boiling water or hot steam.
