Critical Processing Warnings for Hostaform UV90Z XAP2:
Drying for Emission Performance: Drying is recommended to obtain optimum emission performance. If material contacts moisture through improper storage or handling, drying may be necessary to prevent splay and odor issues.
Low Emission Property: To maintain XAP2 low emission characteristics (VDA‑275 <5 ppm), 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.
Material Purity Requirement: Strictly prevent cross‑contamination with other polymer grades. Contamination will degrade the UV stabilized and low emission properties.
Regrind / Recycled Material Notice: We do not recommend adding regrind for this specialty grade. Reprocessing may compromise the UV stability 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.
