CELANESE HOSTAFORM C 2521 G Modified POM Resin

Physical Properties

• Density: With a density of 1.34 g/cc (0.0484 lb/in³) according to ISO 1183, it is a relatively lightweight option for non – structural applications.
• Water Absorption at Saturation: Absorbs 0.80% water at saturation (ISO 62), suggesting potential swelling in wet conditions.
• Melt Flow: Shows a melt flow of 1.5 g/10 min at 190 °C/2.16 kg (ISO 1133), requiring higher processing temperatures for molding.

Polymer Properties:

1. Base Material: Polyoxymethylene (POM) Copolymer
2. Modification Features:
   
   • Stiff – flowing grade for efficient injection molding and extrusion.
   • Exceptional chemical resistance against solvents, fuels, and strong alkalis.
   • High hydrolysis resistance for use in humid environments.
   • Good resistance to thermal and oxidative degradation.
   • Incorporates modifiers for enhanced toughness, even at low temperatures down to – 40 °C.

Applications:

• Automotive: Utilized for door handles and dashboards, resisting cleaning agents, and for under – hood parts enduring heat and engine fluids.
• Industrial Machinery: Employed to make thick – walled parts for gears and structures, ensuring toughness and long – term chemical resistance.
• Building and Construction: Applied in extruding boards and pipes, withstanding indoor and outdoor conditions due to its stiffness and hydrolysis resistance.
