Hostaform S 9363 – Impact Modified POM-C with Improved Modulus & Weld Line Strength

描述

Hostaform S 9363 is an 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 an impact modified grade for demanding applications. Hostaform S 9363 provides good impact strength while improving modulus and weld line strength over standard impact modified grades such as Hostaform S 9064.

Hostaform S 9363 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 (84°C at 1.8 MPa), 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 9363

What makes Hostaform S 9363 the preferred material for impact-resistant applications? Below are its core practical advantages:

Good Impact Strength for Demanding Applications
Hostaform S 9363 provides good impact strength for demanding applications. With notched impact strength of 13 kJ/m² at 23°C and 8 kJ/m² at -30°C, it delivers reliable performance in applications where standard POM grades would fall short.

Improved Modulus for Structural Integrity
Unlike many impact modified grades that sacrifice stiffness for toughness, Hostaform S 9363 maintains a tensile modulus of 2000 MPa – higher than typical impact modified grades. This “rigidity-toughness balance” makes it suitable for structural applications requiring both strength and durability.

Good Weld Line Strength for Complex Geometries
The special formulation provides good weld line strength over standard impact modified grades such as Hostaform S 9064, 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.

Good Heat Resistance
Melting temperature of 165°C and heat deflection temperature of 84°C at 1.8 MPa ensure thermal stability during processing and service.

Excellent Chemical & Hydrolysis Resistance
Outstanding resistance to solvents, fuels, strong alkalis, hydrolysis, fatigue, creep, moisture, and stress cracking.

Good Electrical Properties
Suitable for electrical and electronic applications requiring good electrical insulation.

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)

Recommended processing parameters for Hostaform S 9363:

Critical Processing Warnings for Hostaform S 9363:

• Medium Flow Processing: With MVR of 5.5 cm³/10min, Hostaform S 9363 offers good processability for complex parts. Adjust cycle parameters to maximize throughput while maintaining part quality.

• Drying: Drying is normally not required. If material has come into contact with moisture through improper storage, drying at 80-100°C for 3-4 hours is recommended.

• 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. Max. melt temperature 210°C.

• 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.
