Critical Processing Warnings for Hostaform UV140LG XAP:
Pre‑Drying for Low Gloss Finish: Pre‑drying is required before processing to ensure a low gloss finish. Failure to dry properly may result in surface defects and loss of low gloss characteristics.
Low Gloss Property: To maintain low gloss characteristics, 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 195°C.
Material Purity Requirement: Strictly prevent cross‑contamination with other polymer grades. Contamination will degrade the low gloss, UV stabilized, and low emission properties.
Regrind / Recycled Material Notice: We do not recommend adding regrind for this specialty grade. Reprocessing may compromise the low gloss finish, UV stability, and XAP 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.
