Hostaform C 9021 LS – Low Emission POM-C for Automotive Interior

描述

Hostaform C 9021 LS is a low emission POM-C (Polyoxymethylene Copolymer) injection molding material, genuinely manufactured by Celanese and imported as original product. We supply this grade as an authorized distributor / trader, ensuring full traceability and access to official Celanese technical documentation.

This grade is specifically designed as a low emission / low VOC formulation, making it ideal for applications where air quality and odor are critical concerns – particularly automotive interior components.

The “LS” designation indicates Low Smoke / Low Emission, with reduced volatile organic compounds and low odor characteristics. It is also UV-stabilized for excellent weathering resistance.

It offers high rigidity, hardness, toughness, excellent resilience, good heat distortion temperature (to 100°C), good slip properties, and low moisture absorption. With regular stock availability, we support both trial orders and bulk shipments for automotive, precision engineering, electrical, and appliance applications.

Processing Guidelines (Injection Molding)

The following injection molding parameters are recommended for Hostaform C 9021 LS:

Critical Processing Warnings for Hostaform C 9021 LS:

• Thermal Degradation: POM can decompose at high temperatures, releasing formaldehyde gas. Ensure adequate ventilation and avoid prolonged residence time in the barrel.

• Material Purity: Strictly avoid contamination with other polymers, as this will compromise the low-emission properties and overall performance.

• Regrind/Recycled Material: Adding regrind is not recommended for this low-emission specialty grade. Re-processing may introduce additional volatile compounds and compromise the LS (low emission) properties. If necessary, use a very small percentage (<10%) only with prior validation testing.

• Storage: Store in a cool, dry place and use sealed, original packaging when possible to maintain low-emission characteristics.
