Hostaform C 9021 SW XAP2 LS – Anti-Friction Low Emission POM-C

描述

Hostaform C 9021 SW XAP2 LS is a medium-flowing, anti-friction 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 specially modified with anti-friction additives to provide low wear, low coefficient of friction, and effective prevention of squeaking noise. It also incorporates XAP2 low emission technology for reduced VOC emissions and low odor, along with UV stabilization for excellent weathering resistance.

The “SW” designation stands for Slip & Wear, while “XAP2” and “LS” indicate low emission / low VOC technology.

It is a very hard and rigid, heavy-metal free POM copolymer grade that exhibits outstanding chemical resistance (solvents, fuels & strong alkalis), hydrolysis resistance, fatigue resistance, creep resistance, moisture resistance, and stress cracking resistance. It also maintains toughness down to -40°C, offers good heat distortion temperature (up to 100°C), very good slip/wear properties, excellent resilience, and low moisture absorption. With regular stock availability, we support both trial orders and bulk shipments for precision engineering, automotive, electrical, and appliance applications.

Processing Guidelines (Injection Molding)

The following injection molding parameters are recommended for Hostaform C 9021 SW XAP2 LS:

Critical Processing Warnings for Hostaform C 9021 SW XAP2 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 anti-friction properties, low emission characteristics, and overall performance.

• Regrind/Recycled Material: Adding regrind is not recommended for this specialty grade. Anti-friction additives can degrade during re-processing, compromising mechanical and tribological properties, and may introduce additional volatile compounds that compromise XAP2 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.
