Celanese Hostaform® C 2521 XAP2® POM
Categories: Polymer; Thermoplastic; Acetal (Polyoxymethylene, POM)

Material Notes: Stiff-flowing type for injection molding and extrusion with high impact toughness and good tracking resistance over a high range of temperature; good chemical resistance to solvents, fuel and strong alkalis as well as good hydrolysis resistance; high resistance to thermal and oxidative degradation. With reduced emissions especially for automotive interior application.

Burning rate according to FMVSS 302<100 mm/min (1 mm thickness).

Emissions according to VDA 275<5 mg/kg (natural grades).
Emissions according to VDA 275< 5 mg/kg (colored grades)
