ROBATEC® POM-H TF

Polyoxymethylene homopolymer with PTFE

Semi-crystalline thermoplast | Technical plastic

CharacteristicsOutstanding dimensional stability, good wear resistance, good sliding characteristics, very low water absorption, high mechanical strength and rigidity, hard, high creep strength, good machinability, good weldability
Characteristics compared with POM-C: Somewhat lower expansion coefficient, higher wear resistance, slightly better mechanical characteristics

Excellent resistance to hydrocarbons, alkalis, grease, oil, fuels, ethers, esters, ketones
No resistance to hot water (hydrolysis), halogens, nitrous gases, strong acids, and oxidants

Typical applications: Parts with high demands placed on dimensional stability and appearance
e.g. slide elements, gears, control disks, impellers, bearings, pump parts, valve bodies, snap elements, bearing cages, coupling parts, pump housings, coil formers
