Hostaform EC140XF – Conductive ESD POM-C for Fuel Systems

描述

Hostaform EC140XF is a conductive ESD (electrostatic dissipative) grade of POM-C (Polyoxymethylene Copolymer) injection molding material, 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 specially modified with conductive carbon black to provide permanent electrostatic dissipation, making it ideal for applications requiring the dissipation of static build-up.

The “EC” designation indicates Electrically Conductive, while “XF” identifies this specific ESD formulation. It has an improved resistance to aggressive fuel blends, including hot diesel.

It offers high rigidity (2700 MPa tensile modulus), good toughness (4 kJ/m² notched impact strength), excellent chemical resistance (especially to fuels and solvents), and reliable electrostatic dissipation. With regular stock availability, we support both trial orders and bulk shipments for automotive fuel systems, electronics, and precision engineering applications.

Processing Guidelines (Injection Molding)

The following injection molding parameters are recommended for Hostaform EC140XF:

Critical Processing Warnings for Hostaform EC140XF:

• Pre-drying: Drying is highly recommended for conductive carbon-based ESD grades. Excessive moisture can lead to splay (silver streaking) in molded parts.

• Drying without Desiccant Dryer: Desiccant hopper dryers are not required. For better uniformity especially when using regrind or material stored in open containers, recommended drying is 80°C for 3 hours.

• 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 conductive properties and overall performance.

• Regrind/Recycled Material: Adding regrind is not recommended for this conductive specialty grade. 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.
