Hostaform LW90EWX – Specialty Low Wear POM-C for Tribological Applications

描述

Hostaform LW90EWX is a specialty low wear grade of acetal copolymer (POM-C), genuinely manufactured by Celanese and imported as original product. We supply this grade as an authorized distributor / trader, ensuring full traceability and access to official Celanese technical documentation.

This grade is a medium flowing injection molding grade designed for improved performance including when paired against other thermoplastic resins (PBT, PA, PC, PMMA) or steel. Due to the special wax blend, the material has a good weld line strength.

It 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 (up to 92°C), very good slip/wear properties, excellent resilience, and low moisture absorption. With regular stock availability, we support both trial orders and bulk shipments for automotive, industrial, and precision engineering applications.

Important Notes on Typical Data:

1. Values listed are typical and based on Celanese official data sheets. They do not constitute a product specification.

2. Batch-to-batch variations may occur. Confirm properties with specific batch certificate for critical applications.

3. Final product performance depends on part design, molding conditions, and end-use environment.

4. Celanese original TDS remains the definitive reference. For detailed data, request the latest official TDS for Hostaform LW90EWX from our team.

Processing Guidelines (Injection Molding)

The following injection molding parameters are recommended for Hostaform LW90EWX:

Critical Processing Warnings for Hostaform LW90EWX:

• Thermal Degradation: POM can decompose at high temperatures, releasing formaldehyde gas. Ensure adequate ventilation and avoid prolonged residence time in the barrel. Max. melt temperature 210°C.

• Material Purity: Strictly avoid contamination with other polymers, as this will compromise the low wear properties and overall performance.

• Regrind/Recycled Material: Adding regrind is not recommended for this specialty grade. The special wax blend that provides low wear properties can degrade during re-processing. If necessary, use a very small percentage (<10%) only with prior validation testing.

• Storage: Store in a cool, dry place and use sealed, original packaging when possible.
