Material Advantages of Hostaform S 27242 XAP2

What makes Hostaform S 27242 XAP2 the preferred material for impact-resistant and low emission applications? Below are its core practical advantages:

Good Low Temperature Impact Strength
Hostaform S 27242 XAP2 is specially formulated to maintain impact resistance at low temperatures. With notched impact strength of 5.5 kJ/m² at -30°C, it delivers reliable performance in cold environments where standard POM grades would become brittle and fail.

Good Weld Line Strength
The special formulation provides good weld line 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.

High Flow for Thin-Wall & Complex Parts
With an MVR of 17 cm³/10min, this high flow grade enables rapid filling of thin-wall, long-flow-path complex mold cavities, reducing injection pressure and cycle time while minimizing internal stress in parts. The easy flow characteristics also ensure consistent fill of intricate geometries.

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 Stiffness
With a nominal strain at break of 40% and tensile modulus of 2100 MPa, this material offers a “rigidity-ductility balance” – maintaining structural stiffness while providing the flexibility needed for impact resistance.

Automotive OEM Compliant
Hostaform S 27242 XAP2 meets Mercedes-Benz DBL5404 standard, ensuring compliance with strict automotive OEM requirements.

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

Processing Guidelines (Injection Molding)

Recommended processing parameters for Hostaform S 27242 XAP2:

Critical Processing Warnings for Hostaform S 27242 XAP2:

• High Flow / Thin-Wall Capability: With high flow (MVR 17 cm³/10min), Hostaform S 27242 XAP2 is designed for rapid filling of thin-wall, long-flow-path complex mold cavities. Adjust cycle parameters to maximize throughput while maintaining part quality.

• Drying: Drying is not normally required. If material has come into contact with moisture through improper storage or handling, 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 Line Strength: To maximize weld line 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 line 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.
