Hostaform S 9364 – Highly Impact Modified POM-C for Demanding Applications

Hostaform S 9364 is a highly impact modified 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 provides a significant improvement in impact strength and flexibility over standard impact modified grades such as Hostaform S 9063 and S 9064. Compared with other high impact strength modified copolymers, Hostaform S 9364 offers 50 percent greater impact resistance and 100 percent higher weld line strength.

Hostaform S 9364 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. Available in natural and black, it complies with PFOS, PFOA and ROHS regulations. With regular stock availability, we support both trial orders and large‑volume bulk shipments for automotive, industrial, and consumer applications.

Material Advantages of Hostaform S 9364

What makes Hostaform S 9364 the preferred material for demanding impact-resistant applications? Below are its core practical advantages:

Significant Improvement in Impact Strength & Flexibility
Hostaform S 9364 provides a significant improvement in impact strength and flexibility over standard impact modified grades such as Hostaform S 9063 and S 9064. Compared with other high impact strength modified copolymers, this grade offers 50 percent greater impact resistance and 100 percent higher weld line strength.

Excellent Weld Line Strength for Complex Geometries
The special formulation provides 100 percent higher weld line strength compared with other high impact strength modified copolymers, making it ideal for complex part geometries with multiple gate injection points. This ensures structural integrity at weld lines where standard impact modified grades often show weakness.

Low Melt Flow / High Molecular Weight for Toughness
With an MVR of 4 cm³/10min, Hostaform S 9364 offers low melt flow/high molecular weight characteristics that contribute to its exceptional toughness and impact resistance. The high molecular weight provides superior mechanical properties for demanding applications.

High Ductility with Good Stiffness
With a tensile modulus of 1650 MPa and tensile strain at yield of 16%, this material offers a balance of stiffness and ductility—maintaining structural integrity while providing exceptional impact toughness.

Excellent Impact Resistance at Low Temperatures
Notched impact strength of 21 kJ/m² at 23°C and 11 kJ/m² at -30°C ensure reliable performance in cold environments.

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

Processing Guidelines (Injection Molding & Profile Extrusion)

Recommended processing parameters for Hostaform S 9364:

Critical Processing Warnings for Hostaform S 9364:

• Low Melt Flow Processing: With MVR of 4 cm³/10min, Hostaform S 9364 is a low flow/high molecular weight grade. Ensure adequate injection pressure and mold temperature to achieve complete filling of complex parts.

• Drying: Drying is recommended at 80-100°C for 3 hours. If material has come into contact with moisture through improper storage, drying is necessary to prevent splay and odor.

• Weld Line Strength: To maximize weld line strength, ensure proper melt temperature and injection speed for optimal polymer chain entanglement at weld lines.

• 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 impact properties and weld line strength. 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.
