Critical Processing Warnings for Hostaform UV270Z XAP2:
High Flow Processing: With MVR of 24 cm³/10min – among the highest flow UV stabilized POM grades – Hostaform UV270Z XAP2 is designed for rapid filling of thin‑wall, complex mold cavities. Adjust cycle parameters to maximize throughput while maintaining part quality.
Drying: Drying is generally not required due to low moisture absorption. However, to achieve low emission values, pre‑drying using a recirculating air dryer (100°C / max. 40 mm layer / 3 to 4 hours) is recommended.
Low Emission Property: To maintain XAP2 low emission characteristics meeting VDA 275 requirements, avoid contamination and ensure proper processing conditions.
UV Stabilization Property: The 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. Max. melt temperature 210°C.
Material Purity Requirement: Strictly prevent cross‑contamination with other polymer grades. Contamination will degrade the UV stabilized, high flow, and low emission properties.
Regrind / Recycled Material Notice: We do not recommend adding regrind for this specialty grade. Reprocessing may compromise the UV stability, flow properties, and XAP2 low emission characteristics. If regrind usage is mandatory, keep percentage below 10% and complete pre‑validation testing first.
Assembly Considerations: Hostaform UV270Z XAP2 can be injection molded in one shot, and then snap‑fitted or ultrasonically inserted in the support element. Consider gate and runner design to optimize flow and part quality for assembly operations.
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.
