描述

Hostaform C 9021 M XAP2 is a molybdenum disulphide (MoS₂) modified, 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 modified with molybdenum disulphide (MoS₂) , a solid lubricant that provides extremely low friction and excellent wear resistance for demanding sliding applications. It also incorporates XAP2 low emission technology for reduced VOC emissions and low odor.

The “M” designation indicates tribological modification with MoS₂, while “XAP2” indicates low emission technology. Together, they deliver outstanding slip properties, high rigidity and hardness, and compliance with automotive interior air quality standards.

It exhibits outstanding chemical (solvents, fuels & strong alkalis), hydrolysis, fatigue, creep, moisture and stress cracking resistance. It also maintains toughness down to -40°C and offers higher stability to thermal and oxidative degradation compared to acetal homopolymers. With regular stock availability, we support both trial orders and bulk shipments for automotive interior, industrial, and precision engineering applications.

Critical Processing Warnings for Hostaform C 9021 M XAP2:

  • 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 MoS₂-modified tribological properties and XAP2 low emission characteristics.

  • Regrind/Recycled Material: Adding regrind is not recommended for this specialty grade. MoS₂ 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.
