Critical Processing Warnings for Hostaform MR130AR:
Pre-Drying: Pre-drying is required for this material. Standard drying conditions are 100-130°C for 2-4 hours in a dehumidified dryer. If material has come into contact with moisture through improper storage or handling, drying is necessary to prevent splay and odor.
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 acid resistance and overall performance.
Regrind / Recycled Material Notice: We do not recommend adding regrind for this specialty grade. Reprocessing may compromise the acid resistance and mechanical properties. 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.
