Hostaform S 27064 – High Flow Impact Modified POM-C

描述

Hostaform S 27064 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 high toughness and reduced emissions. It is an easy flowing, elastomer-containing injection molding type developed for thin-walled molded parts with high energy-absorbing capacity.

Hostaform S 27064 offers high toughness with slightly lower hardness, rigidity and chemical resistance than the basic type, while exhibiting high resistance to thermal and oxidative degradation. It is available in natural and colored grades including 10/1570. We hold regular stock, supporting small trial orders and large‑volume bulk shipments for automotive, consumer, and industrial applications.

Material Advantages of Hostaform S 27064

What makes Hostaform S 27064 the preferred material for impact-resistant thin-wall applications? Below are its core practical advantages:

Super-Toughened Impact Performance
With unnotched impact strength of 150 kJ/m² at 23°C and 110 kJ/m² at -30°C, Hostaform S 27064 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 18-19 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 27064 exhibits high resistance to thermal and oxidative degradation, maintaining stability during long-term high-temperature use or multiple processing cycles.

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 1500-1700 MPa and tensile stress at yield of 41-44 MPa, this material offers moderate stiffness with excellent ductility (nominal strain at break of 35%) – the flexibility gained from elastomer modification makes it more suitable for impact and vibration applications.

Low Emission Performance
Emission according to VDA 275 is <10 mg/kg for both natural and colored grades, making it suitable for automotive interior applications with strict cabin air quality requirements.

Automotive Flammability Compliant
UL94 HB rated and meets FMVSS 302 automotive interior flammability standard (<100 mm/min) for thickness >1 mm.

Good Electrical Insulation Properties
Volume resistivity of 1E11 Ohm·m and CTI of 600V, suitable for electrical and electronic applications requiring good electrical insulation.

Heavy‑Metal Free
Environmentally friendly formulation.

Batch‑to‑Batch Consistency
Celanese manufactures this grade under strict ISO quality standards for consistent property across shipments.

Processing Guidelines (Injection Molding)

Recommended processing parameters for Hostaform S 27064:

Critical Processing Warnings for Hostaform S 27064:

• High Flow / Thin-Wall Capability: With high flow (MVR 18-19 cm³/10min), Hostaform S 27064 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.

FAQ

Q1: What is Hostaform S 27064 and what is it used for?
A: Hostaform S 27064 is an easy flowing, elastomer-containing impact modified POM‑C (Polyoxymethylene Copolymer) based on HOSTAFORM C 27021. It is designed for thin-walled molded parts with high energy-absorbing capacity. It is widely used in automotive interior components (door panels, instrument panels, seat belts, storage boxes), thin-wall high-energy absorbing structures, electrical & electronics (connectors, switches, housings), and consumer goods (toys, sports equipment, bottle caps).

Q2: What does “S 27064” mean in the grade name?
A: S indicates super-toughened impact resistance – the “rubber grade” or “super-tough grade” within the POM family. 27064 is the specific grade designation based on HOSTAFORM C 27021.

Q3: What is the difference between Hostaform S 27063 and S 27064?
A: Both are impact-modified POM grades.

A: Melt‑volume‑flow‑rate equals 18-19 cm³/10min measured under 190°C / 2.16 kg test condition.

Q6: What is the density of this material?
A: The density is 1.37 g/cm³.

Q7: Is this material suitable for automotive applications?
A: Yes. Hostaform S 27064 meets FMVSS 302 automotive interior flammability standard (<100 mm/min) for thickness >1 mm and is UL94 HB rated. It also features low emissions (VDA 275 <10 mg/kg).

Q8: What is the UL flammability rating?
A: UL94 HB rated for natural color at thickness >1.57 mm. FMVSS 302 burning rate is <100 mm/min for thickness >1 mm.

Q9: Is drying required before processing?
A: Drying is recommended to avoid surface silver streaks or bubble defects. Recommended drying: 100-120°C for 3-4 hours.

Q10: What are recommended processing‑temperature windows?
A: Zone 1 (rear) temperature: 170-180°C; Hopper temperature: 20-30°C; Optimum melt temperature: 190-200°C; Optimum mold temperature: 60-80°C.

Q11: What is the ECO-B version?
A: The ECO-B version of Hostaform S 27064 offers the same properties and performance but is produced with sustainability in mind using a mass-balance approach with biogenic feedstocks, ISCC Plus certified.

Q12: Can I buy this material and what is lead‑time?
A: Yes. Submit your inquiry via our quick inquiry form or email ruiqingchem@gmail.com, specify quantity, application and delivery address. Regular orders 1‑5 tons ship within 7‑10 working days after payment confirmation. Large‑volume or urgent orders can be negotiated separately.

Q13: What are limitations?
A: POM‑C does not resist strong mineral acids, powerful oxidizing agents, or continuous exposure to hot water >80°C. Due to elastomer modification, this grade has slightly lower chemical resistance than unmodified POM types.
