Material Advantages of Hostaform S 27064 XAP

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

Elastomer-Toughened Technology for High Impact Resistance
With unnotched impact strength of 150 kJ/m² at 23°C and 110 kJ/m² at -30°C, Hostaform S 27064 XAP 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. This makes it suitable for safety protection components and impact energy-absorbing structures.

High Flow for Thin-Wall & Complex Parts
With an MVR of 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. This is particularly beneficial for high-volume automotive interior production.

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. Puncture energy of 35 J at 23°C demonstrates exceptional energy absorption.

XAP Low Emission Technology
The “XAP” designation indicates Celanese’s proprietary low emission technology, with emission according to VDA 275 <10 mg/kg (natural and colored grades). This makes it especially suitable for automotive interior applications with strict cabin air quality requirements, such as door panels, instrument panels, and storage boxes.

Excellent Thermal & Oxidative Stability
Hostaform S 27064 XAP 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 and heat deflection temperature of 77°C at 1.8 MPa ensure thermal stability during processing and service.

Automotive Flammability Compliant
Burning rate ISO 3795 and FMVSS 302 <100 mm/min for thickness >1 mm, making it suitable for automotive interior applications.

Heavy‑Metal Free
Environmentally friendly, heavy‑metal‑free formulation.

Processing Guidelines (Injection Molding)

Recommended processing parameters for Hostaform S 27064 XAP:

Critical Processing Warnings for Hostaform S 27064 XAP:

• High Flow / Thin-Wall Capability: With high flow (MVR 19 cm³/10min), Hostaform S 27064 XAP 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 achieve optimal low emission performance and avoid surface defects. Recommended drying: 100-120°C for 3-4 hours.

• Low Emission Property: To maintain XAP low emission characteristics, avoid contamination and ensure proper processing conditions.

• 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 low emission properties.

• Regrind / Recycled Material Notice: We do not recommend adding regrind for this specialty grade. Reprocessing may compromise the elastomer-modified impact properties, flow characteristics, and XAP low emission 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 to maintain low emission characteristics.
