Hostaform S 9244 XAP2 – Impact Modified Low Emission POM-C

描述

Hostaform S 9244 XAP2 is an impact modified, elastomer-containing POM‑C (Polyoxymethylene Copolymer) injection molding grade, genuinely manufactured by Celanese and imported as original product. As an authorized distributor and trader, we supply genuine material with full traceability and direct access to official Celanese technical documentation.

This unfilled acetal copolymer is an impact modified injection molding type containing elastomer modifiers that deliver higher impact strength than standard acetal copolymers. The “XAP2” designation indicates Celanese’s low emission technology, with emission according to VDA 275 <5 mg/kg.

Hostaform S 9244 XAP2 offers a unique balance of impact resistance, good weld strength, and reduced emissions—making it an ideal choice for automotive interior applications where cabin air quality is critical. Compared to the basic type HOSTAFORM C 9021, this grade exhibits slightly lower hardness, rigidity, and chemical resistance, but delivers significantly higher impact strength and good weld strength.

We hold regular stock of Hostaform S 9244 XAP2, supporting small trial orders and large‑volume bulk shipments for automotive, industrial, and consumer applications.

Material Advantages of Hostaform S 9244 XAP2

What makes Hostaform S 9244 XAP2 the preferred material for impact-resistant and low emission applications? Below are its core practical advantages:

Higher Impact Strength vs. Standard POM
Hostaform S 9244 XAP2 offers higher impact strength than the basic type HOSTAFORM C 9021. With notched impact strength of 18 kJ/m² at 23°C and 12 kJ/m² at -30°C, it delivers reliable performance in demanding applications where standard POM grades would fall short.

Good Weld Strength for Complex Geometries
The special elastomer formulation provides good weld strength, making it ideal for complex part geometries with multiple gate injection points. This ensures structural integrity at weld lines where standard POM grades often show weakness.

XAP2 Low Emission Technology
The “XAP2” designation indicates Celanese’s proprietary low emission technology, with emission according to VDA 275 <5 mg/kg. This makes it especially suitable for automotive interior applications with strict cabin air quality requirements.

High Ductility with Good Toughness
With a nominal strain at break of >50% and notched impact strength of 18 kJ/m² at 23°C, this material offers exceptional toughness while maintaining high ductility. The high ductility allows parts to deform without fracturing under impact or stress.

Good Heat Resistance
Melting temperature of 166°C and heat deflection temperature of 68°C at 1.8 MPa ensure thermal stability during processing and service.

Good Electrical Properties
Volume resistivity of 1E11 Ω·m and CTI of 600V make it suitable for electrical and electronic applications.

Heavy‑Metal Free
Environmentally friendly, heavy‑metal‑free formulation.

Batch‑to‑Batch Consistency
Celanese manufactures this grade under strict ISO quality standards for consistent property across shipments.

Processing Guidelines (Injection Molding)

Recommended processing parameters for Hostaform S 9244 XAP2:

Critical Processing Warnings for Hostaform S 9244 XAP2:

• Low Melt Flow Processing: With MVR of 1.4 cm³/10min, Hostaform S 9244 XAP2 is a low flow grade. Ensure adequate injection pressure and mold temperature to achieve complete filling of complex parts.

• Drying: Drying is not normally required. If material has come into contact with moisture through improper storage, drying at 100°C for 3-4 hours is recommended.

• Low Emission Property: To maintain XAP2 low emission characteristics (VDA 275 <5 mg/kg), avoid contamination and ensure proper processing conditions.

• Thermal Degradation Risk: POM‑based material can decompose under excessive heat and release formaldehyde vapors. Guarantee sufficient ventilation; avoid overly long barrel residence times. Max. melt temperature 200°C.

• Material Purity Requirement: Strictly prevent cross‑contamination with other polymer grades. Contamination will degrade the impact-modified and low emission properties.

• Weld Strength: To maximize weld strength, ensure proper melt temperature and injection speed for optimal polymer chain entanglement at weld lines.

• Regrind / Recycled Material Notice: We do not recommend adding regrind for this specialty grade. Reprocessing may compromise the impact properties, weld strength, and XAP2 low emission characteristics. If regrind usage is mandatory, keep percentage below 10% and complete pre‑validation testing first.

• Storage Guidance: Store pellets in cool, dry conditions; keep sealed in original factory packaging whenever possible to maintain low emission characteristics.
