Hostaform MR130ACS – Acid Resistant POM-C for Demanding Applications

描述

Hostaform MR130ACS is a general purpose, acid resistant POM‑C (Polyoxymethylene Copolymer) grade, genuinely manufactured by Celanese and imported as original product. As an authorized distributor and trader, we supply genuine material with full traceability and direct access to official Celanese technical documentation.

This unfilled acetal copolymer is formulated with enhanced acid stabilization, demonstrating improved performance over standard acetals after intermittent exposure to acidic cleaners. The medium-high viscosity (MVR 12 cm³/10min) offers excellent flowability for injection molding of complex part geometries while maintaining outstanding mechanical properties.

Hostaform MR130ACS is a very hard and rigid, heavy-metal free POM copolymer grade that exhibits outstanding chemical resistance, hydrolysis resistance, fatigue resistance, creep resistance, moisture resistance, and stress cracking resistance. It is suitable for injection molding processingand is available in natural, 60/5604, and 10/5358 BLACK colors. We hold regular stock, supporting small trial orders and large‑volume bulk shipments for demanding end‑users.

Processing Guidelines (Injection Molding)

Recommended processing parameters for Hostaform MR130ACS:

Critical Processing Warnings for Hostaform MR130ACS:

• Drying: Drying is recommended for this material. Standard drying conditions are 82°C (180°F) for 3 hours. If material has come into contact with moisture through improper storage or handling or through regrind use, drying may be 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 210°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.
