Hostaform M30RS – High Viscosity POM-C for Extrusion Shapes & Thick-Wall Parts

描述

Hostaform M30RS is a high viscosity, special grade POM‑C (Polyoxymethylene Copolymer) developed specifically for extrusion applications, 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 targeted for extrusion shapes (rod, bar, plate, etc.) free of center porosity in large diameters and thicknesses with improved processing. The high viscosity (MVR 2.2 cm³/10min) provides outstanding melt strength essential for maintaining dimensional stability during extrusion of thick cross-sections.

Hostaform M30RS is a very hard and rigid, heavy-metal free POM copolymer grade that exhibits outstanding chemical resistance (solvents, fuels & strong alkalis), hydrolysis resistance, fatigue resistance, creep resistance, moisture resistance, and stress cracking resistance. It also exhibits toughness, very good slip/wear properties, excellent resilience, and low moisture absorption. It is suitable for injection molding, film extrusion, profile extrusion, sheet extrusion, other extrusion, blow molding, and calendering. We hold regular stock, supporting small trial orders and large‑volume bulk shipments for extrusion and demanding end‑users.

Processing Guidelines (Extrusion & Injection Molding)

Recommended processing parameters for Hostaform M30RS:

Critical Processing Warnings for Hostaform M30RS:

• Extrusion Considerations: Hostaform M30RS is targeted for extrusion shapes (rod, bar, plate, etc.) free of center porosity in large diameters and thicknesses. Standard extruders with grooved feed zone and short compression screws (minimum 25 D) are recommended.

• Screw Selection: Standard reciprocating screw injection molding machines with a high compression screw (minimum 3:1 and preferably 4:1) and low back pressure (0.35 MPa/50 PSI) are favored. Using a low compression screw (e.g., general purpose 2:1 compression ratio) can result in unmelted particles and poor melt homogeneity. Using high back pressure to make up for a low compression ratio may lead to excessive shear heating and deterioration of the material.

• Profile & Sheet 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: Drying is generally not required because acetal copolymers are not hygroscopic nor degraded by moisture during processing. Excessive moisture can lead to splay (silver streaking) in molded parts. 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. Melt temperature should never exceed 230°C.

• Material Purity Requirement: Strictly prevent cross‑contamination with other polymer grades. Contamination will degrade the high‑viscosity and extrusion 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 and extrusion 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.
