Hostaform® C 2521 LS 40/5295

Technical Datasheet | Supplied by Celanese

HOSTAFORM® C 2521 LS 40/5295 by Celanese is a stiff flowing type, very hard and rigid, heavy-metal free POM (polyoxymethylene) copolymer grade. It exhibits outstanding chemical (solvents, fuels & strong alkalis)-, hydrolysis-, fatigue-, creep-, moisture- and stress cracking resistance. It provides toughness (up to -40°C), good heat distortion temperature (up to 100°C) and very good slip/ wear properties. It offers excellent resilience, low moisture absorption and higher stability to thermal and oxidative degradation compared to acetal homopolymers. Hostaform® C 2521 LS 40/5295 is suitable for injection molding of thick-walled, void-free molded parts and extrusion of boards and pipes.
