[Type] Acetals (polyformaldehyde or polyoxymethylene) [Uses] Housings, impellors and other parts for water pumps, washing machines and extractor fans. Instrument panels and housings for cars. Also used for plumbing fittings, pipe clips, bearings, cams and gears. Window catches and hinges and parts for aerosol containers.
Strong and stiff. Creep resistant with good fatigue endurance. High crystallinity and high melting point make it suitable for replacing some metals. Good electrical properties and resistant to alkalis and many solvents. Attacked by mineral acids .Slight water absorption. It is adversely affected by prolonged exposure to ultra-violet light and is not recommended for outdoor use or in strong sunlight.
