Critical Processing Warnings for Hostaform S 27072 WS 10/1570:
Weather Resistance Performance: To maintain the UV stabilization and weather resistance properties, avoid contamination and ensure proper processing conditions.
Drying: Drying is recommended to achieve optimal performance and avoid surface defects. Recommended drying: 80-100°C for 3 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 impact-modified and weather resistant properties.
Regrind / Recycled Material Notice: We do not recommend adding regrind for this specialty grade. Reprocessing may compromise the impact properties, weather resistance, and flow 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 UV stabilization effectiveness.
Lower Chemical Resistance: This grade has lower chemical resistance than the basic type HOSTAFORM C 27021. Consider this when selecting for chemical exposure applications.
Color Availability: This grade is only available in black (10/1570) .
