Hostaform S 9364 WS 10/1570 – UV Stabilized Impact Modified POM-C

描述

Hostaform S 9364 WS 10/1570 is a highly impact modified, UV stabilized acetal copolymer (POM-C) 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 a highly impact modified grade for demanding applications that also need improved resistance to UV exposure. The “WS” designation stands for Weather Stabilized / UV Stabilized, indicating enhanced weathering resistance. Hostaform S 9364 WS 10/1570 provides a significant improvement in impact strength and flexibility over standard impact modified grades.

Hostaform S 9364 WS 10/1570 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, good heat distortion temperature, very good slip/wear properties, excellent resilience, and low moisture absorption. This grade is only available in black. With regular stock availability, we support both trial orders and large‑volume bulk shipments for automotive, outdoor, industrial, and consumer applications.

Material Advantages of Hostaform S 9364 WS 10/1570

What makes Hostaform S 9364 WS 10/1570 the preferred material for impact-resistant and UV-exposed applications? Below are its core practical advantages:

UV Stabilization for Outdoor Durability
The “WS” (Weather Stabilized) designation indicates UV stabilization, providing enhanced weathering resistance and long-term color stability for demanding outdoor and automotive applications. This makes it suitable for components exposed to direct sunlight and harsh environmental conditions.

Significant Improvement in Impact Strength & Flexibility
Hostaform S 9364 WS 10/1570 provides a significant improvement in impact strength and flexibility over standard impact modified grades. With notched impact strength of 16 kJ/m² at 23°C and 7 kJ/m² at -30°C, it delivers reliable performance in demanding applications where standard POM grades would fall short.

High Ductility for Demanding Applications
With a tensile strain at yield of 20%, this material offers exceptional ductility, allowing parts to deform without fracturing under impact or stress. This makes it ideal for applications requiring flexibility and durability.

Good Stiffness with Impact Resistance Balance
With a tensile modulus of 1500 MPa and tensile stress at yield of 41 MPa, Hostaform S 9364 WS 10/1570 provides a balance of stiffness and impact resistance—maintaining structural integrity while delivering exceptional impact toughness.

Good Heat Resistance
Melting temperature of 165-166°C and heat deflection temperature of 75°C at 1.8 MPa ensure thermal stability during processing and service.

Low Moisture Absorption
Humidity absorption of only 0.25% and water absorption of 0.8% ensure dimensional stability across varying environmental conditions.

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

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

Processing Guidelines (Injection Molding & Profile Extrusion)

Recommended processing parameters for Hostaform S 9364 WS 10/1570:

Critical Processing Warnings for Hostaform S 9364 WS 10/1570:

• Medium Flow Processing: With MVR of 4.5 cm³/10min, Hostaform S 9364 WS 10/1570 offers good processability for complex parts. Adjust cycle parameters to maximize throughput while maintaining part quality.

• Temperature Limits: Do not heat over 205°C (400°F) to avoid burning and discoloring the product.

• Drying: Drying is not normally required. If material has come into contact with moisture through improper storage or handling or through regrind use, drying to prevent splay and odor problems is recommended. Recommended drying: 100°C for 3-4 hours.

• UV Stabilization Property: The WS UV stabilization additives are fully dispersed in the base resin; standard processing conditions will not degrade UV performance. Avoid contamination that could compromise UV stability.

• 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 200°C.

• Material Purity Requirement: Strictly prevent cross‑contamination with other polymer grades. Contamination will degrade the impact-modified and UV stabilized properties.

• Regrind / Recycled Material Notice: We do not recommend adding regrind for this specialty grade. Reprocessing may compromise the impact properties, UV stabilization, and overall performance. 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 UV stabilization effectiveness.
