HHostaform S 27063 – High Flow Impact Modified POM-C

描述

Hostaform S 27063 is an easy flowing, elastomer-containing impact modified 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 based on HOSTAFORM C 27021 with higher impact strength and reduced emissions for demanding applications. The “S” designation indicates super-toughened impact resistance, making it the “rubber grade” or “super-tough grade” within the POM family.

Hostaform S 27063 is an easy flowing, elastomer-containing injection molding type developed for thin-walled molded parts with higher energy-absorbing capacity. It offers high impact strength with slightly lower hardness, rigidity and chemical resistance than the basic type. The material also exhibits high resistance to thermal and oxidative degradation. We hold regular stock, supporting small trial orders and large‑volume bulk shipments for automotive, consumer, and industrial applications.

Material Advantages of Hostaform S 27063

What makes Hostaform S 27063 the preferred material for impact-resistant thin-wall applications? Below are its core practical advantages:

Super-Toughened Impact Performance
With unnotched impact strength of 140 kJ/m² at 23°C and 90 kJ/m² at -30°C, Hostaform S 27063 delivers exceptional impact resistance that standard POM grades cannot match. The elastomer modification provides a “rigidity-toughness balance” – maintaining POM’s base rigidity while significantly enhancing impact capability.

High Flow for Thin-Wall & Complex Parts
With an MVR of 20 cm³/10min, this high flow grade enables rapid filling of thin-wall, long-flow-path complex mold cavities, reducing injection pressure and cycle time while minimizing internal stress in parts.

High Energy-Absorbing Capacity
Specifically designed for thin-walled molded parts with higher energy-absorbing capacity, making it ideal for safety protection components and impact energy-absorbing structures.

Excellent Thermal & Oxidative Stability
Hostaform S 27063 exhibits high resistance to thermal and oxidative degradation, maintaining stability during long-term high-temperature use or multiple processing cycles, ensuring long product service life and processing stability.

Good Heat Resistance
Melting temperature of 166°C ensures thermal stability during processing and service.

Moderate Stiffness for Impact Applications
With a tensile modulus of 1950 MPa and yield stress of 54 MPa, this material offers moderate stiffness with excellent ductility (nominal strain at break of 30%) – the flexibility gained from elastomer modification makes it more suitable for impact and vibration applications.

Automotive Flammability Compliant
Natural color products achieve UL94 HB rating at thickness >1.57 mm and meet FMVSS 302 automotive interior flammability standard (<100 mm/min) for thickness >1 mm.

Processing Guidelines (Injection Molding)

Recommended processing parameters for Hostaform S 27063:

Critical Processing Warnings for Hostaform S 27063:

• High Flow / Thin-Wall Capability: With high flow (MVR 20 cm³/10min), Hostaform S 27063 is designed for rapid filling of thin-wall, long-flow-path complex mold cavities. Adjust cycle parameters to maximize throughput while maintaining part quality.

• Drying: Drying is recommended to avoid surface silver streaks or bubble defects. Recommended drying: 100-120°C for 3-4 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 properties.

• Regrind / Recycled Material Notice: We do not recommend adding regrind for this specialty grade. Reprocessing may compromise the elastomer-modified impact properties 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.
