Hostaform S 9243 XAP2 LS – Impact Modified UV Stabilized POM-C

描述

Hostaform S 9243 XAP2 LS is an impact modified, UV stabilized, 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 a rigid, heavy-metal free, impact modified grade containing elastomer modifiers that deliver higher impact strength than standard acetal copolymers. The “LS” designation indicates UV stabilization (Light Stabilized), providing enhanced weathering resistance for demanding outdoor and automotive applications. The “XAP2” designation indicates Celanese’s low emission technology, with emission according to VDA 275 <5 mg/kg.

Hostaform S 9243 XAP2 LS offers a unique combination of impact resistance, good weld strength, UV stability, and reduced emissions—making it an ideal choice for automotive interior and exterior applications where cabin air quality and long-term weatherability are 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 9243 XAP2 LS, supporting small trial orders and large‑volume bulk shipments for automotive, industrial, and consumer applications.

Material Advantages of Hostaform S 9243 XAP2 LS

What makes Hostaform S 9243 XAP2 LS the preferred material for impact-resistant, UV-stabilized, and low emission applications? Below are its core practical advantages:

Higher Impact Strength vs. Standard POM
Hostaform S 9243 XAP2 LS offers higher impact strength than the basic type HOSTAFORM C 9021. With notched impact strength of 15 kJ/m² at 23°C and 9 kJ/m² at -30°C, it delivers reliable performance in demanding applications where standard POM grades would fall short.

UV Stabilization (LS) for Outdoor Durability
The “LS” (Light Stabilized) designation indicates UV stabilization, providing enhanced weathering resistance and long-term color stability for demanding outdoor and automotive applications. This makes it suitable for components exposed to direct sunlight and harsh environmental conditions.

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.

Good Stiffness with High Ductility
With a tensile modulus of 1950 MPa and nominal strain at break of 40%, this material offers a balance of stiffness and ductility—maintaining structural integrity while providing the flexibility needed for impact resistance.

Automotive Flammability Compliant
Burning rate according to FMVSS 302 <100 mm/min (1 mm thickness), making it suitable for automotive interior applications.

Good Heat Resistance
Melting temperature of 166°C and heat deflection temperature of 75°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, suitable for electrical and electronic applications.

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

Processing Guidelines (Injection Molding)

Recommended processing parameters for Hostaform S 9243 XAP2 LS:

Critical Processing Warnings for Hostaform S 9243 XAP2 LS:

• Medium Flow Processing: With MVR of 4 cm³/10min, Hostaform S 9243 XAP2 LS offers good processability for complex parts. Adjust cycle parameters to maximize throughput while maintaining part quality.

• Drying: Drying is normally not necessary. However, should there be surface moisture (condensate) on the molding compound as a result of incorrect storage, drying is required. A circulating air drying cabinet can be used for this purpose. Recommended drying: 100°C for 3-4 hours.

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

• UV Stabilization: The LS UV stabilization additives are fully dispersed in the base resin; standard processing conditions will not degrade UV performance.

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

• Material Purity Requirement: Strictly prevent cross‑contamination with other polymer grades. Contamination will degrade the impact-modified, UV stabilized, 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, UV stabilization, 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 and UV stabilization effectiveness.
