Hostaform C 9021 TF – PTFE-Modified Low Friction POM-C

描述

Hostaform C 9021 TF is a PTFE-modified 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 modified with PTFE (polytetrafluoroethylene) to provide an exceptionally low coefficient of friction, making it ideal for demanding sliding applications.

The “TF” designation indicates tribological modification with PTFE, delivering very low friction, good wear resistance, and self-lubricating properties.

It offers high rigidity, good toughness, outstanding chemical resistance (solvents, fuels & strong alkalis), good hydrolysis resistance, and high resistance to thermal and oxidative degradation. With regular stock availability, we support both trial orders and bulk shipments for automotive, precision engineering, and industrial applications.

Processing Guidelines (Injection Molding)

The following injection molding parameters are recommended for Hostaform C 9021 TF:

Critical Processing Warnings for Hostaform C 9021 TF:

• 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 PTFE-modified tribological properties.

• Regrind/Recycled Material: Adding regrind is not recommended for this PTFE-modified specialty grade. PTFE additives can degrade during re-processing, compromising mechanical and tribological properties. 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.

FAQ

Q1: What is Hostaform C 9021 TF and what is it used for?
A: It is a PTFE-modified POM-C (Polyoxymethylene Copolymer) injection molding material that provides a very low coefficient of friction for sliding combinations. It is specifically designed for wear applications against plastics, metal, glass, or ceramic mating surfaces where silicone lubricants cannot be tolerated. It is widely used in automotive (seat adjustment mechanisms, window regulators), precision engineering (low-friction gears, bearings, guide rails), industrial machinery, electrical & electronics, and consumer goods applications.

Q2: What does “TF” mean in the grade name?
A: TF stands for Tribological modification with PTFE (polytetrafluoroethylene). This indicates that the material is modified with PTFE to provide a very low coefficient of friction and good wear resistance. The resin identification code is POM+PTFE.
