Hostaform C 9021 S OEK – 20% Silicone Concentrate for POM

描述

Hostaform C 9021 S OEK is a specialty silicone concentrate based on acetal copolymer (POM), 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 product is a ~20% loaded silicone concentrate designed to be used in conjunction with other Celanese acetal copolymer products to reduce friction and improve wear performance.

The “S” designation indicates silicone modification, while “OEK” identifies this specific concentrate formulation. It is not meant to be used as a stand-alone product.

When blended with standard POM grades, it significantly enhances tribological properties (reduced friction and improved wear resistance). It retains the outstanding chemical resistance (solvents, fuels & strong alkalis), hydrolysis resistance, toughness, and high resistance to thermal and oxidative degradation of the base POM copolymer. With regular stock availability, we support both trial orders and bulk shipments.

Key Features

Hostaform C 9021 S OEK offers the following key performance benefits as a concentrate:

• ~20% Silicone Concentrate – High loading of silicone for effective friction reduction and wear improvement when blended.

• Friction Reduction – Significantly reduces the coefficient of friction in finished parts.

• Improved Wear Performance – Enhances abrasion resistance and extends component life.

• Tribological Additive – Designed specifically to improve the tribological (friction and wear) properties of POM compounds.

• Versatile Blending – Can be used in conjunction with other Celanese acetal copolymer products.

• Not a Stand-Alone Product – Specifically designed as a masterbatch/concentrate for blending, not for direct use.

• Outstanding Chemical Resistance – Base resin provides good chemical resistance to solvents, fuel and strong alkalis as well as good hydrolysis resistance.

• High Thermal & Oxidative Stability – Base resin provides high resistance to thermal and oxidative degradation.

• Regulatory Compliance – Complies with RoHS and REACH. Full SDS available upon request.

Typical Applications

The primary application of Hostaform C 9021 S OEK is as an additive concentrate for injection molding compounds. When blended with standard POM, the resulting material is suitable for a wide range of tribological applications:

Typical Properties (ISO Standards)

Typical properties of Hostaform C 9021 S OEK measured per ISO standards are listed below. Please note this product is a concentrate and typical properties of the final blend will vary based on the let-down ratio.

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. Celanese original TDS remains the definitive reference. For detailed data, request the latest official TDS for Hostaform C 9021 S OEK from our team.

Processing Guidelines (Injection Molding – as a Concentrate)

The following parameters are recommended for processing Hostaform C 9021 S OEK when used as a concentrate for blending.

Critical Processing Warnings for Hostaform C 9021 S OEK:

• Not a Stand-Alone Product: This material is a concentrate and must be blended with other POM grades. It is not intended for use as a neat resin.

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

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

• Regrind/Recycled Material: Adding regrind is not recommended for this specialty concentrate. Silicone additives and the base polymer can degrade during re-processing, compromising the effectiveness of the concentrate. 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.
