Critical Processing Warnings for Hostaform M25IE:
Calendering Considerations: Hostaform M25IE is a special grade targeted for calendering, providing sheets with a high gloss and smooth surface. Standard extruders with grooved feed zone and short compression screws (minimum 25 D) are recommended.
Sheet Extrusion: For sheet extrusion, follow standard extrusion parameters. General drying is not necessary due to low moisture absorption.
Profile Extrusion: For profile extrusion, melt temperature of 180-190°C is recommended. For very thick wall thickness profiles, after-annealing at 130-140°C for 10 min/mm thickness is recommended to reduce internal stress.
Drying: General drying is not necessary due to low moisture absorption. In case of bad storage conditions (water contact or condensed water), use a recirculating air dryer at 100-120°C for 3-6 hours.
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 high‑viscosity, high-gloss, and calendering performance.
Regrind / Recycled Material Notice: We do not recommend adding regrind for this high‑viscosity specialty grade. Reprocessing reduces molecular weight and compromises the core melt‑strength, high-gloss surface, and calendering advantages. 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.
