Hostaform® C 9021 MD NATURAL

Technical Datasheet | Supplied by Celanese
Hostaform® C 9021 MD NATURAL is a very hard and rigid, heavy-metal free POM (polyoxymethylene) copolymer grade reinforced with stainless steel. It is based on Hostaform® C 9021. Exhibits outstanding chemical (solvents, fuels & strong alkalis)-, hydrolysis-, fatigue-, creep-, moisture- and stress cracking resistance. Also exhibits toughness (up to -40°C), good heat distortion temperature (up to 100°C), very good slip/ wear properties, excellent resilience, low moisture absorption and higher stability to thermal and oxidative degradation compared to acetal homopolymers. Also shows easy colorization. Capable of being identified by metal detectors. It can be processed by injection molding.
