描述
Hostaform C 9021 AW POM is a wear-resistant POM-C (Polyoxymethylene Copolymer) injection molding grade supplied by Celanese. This grade is specially formulated to provide excellent tribological performance, featuring low friction coefficient and high wear resistance for moving parts and sliding applications. It retains the mechanical strength, stiffness, and dimensional stability of standard POM-C while significantly enhancing abrasion resistance in demanding environments. This makes it an ideal choice for bearings, gears, and precision mechanisms where long-term reliability is critical. With global stock availability and fast delivery, we support both sample orders and bulk shipments for automotive, industrial machinery, and consumer applications.

Processing Guidelines (Injection Molding)
| Parameter | Recommended Setting |
|---|---|
| Pre-drying | 80–100°C for 2–4 hours (recommended to avoid surface silver streaks) |
| Barrel Temperature | 180–210°C (nozzle temperature recommended at 190–200°C) |
| Mold Temperature | 80–100°C (higher mold temperature improves crystallinity and surface quality) |
| Injection Pressure | 80–150 MPa (medium-to-high, ensures complete filling of thin-wall sections) |
| Screw Speed | Medium speed (avoid excessive shear degradation) |
Note: As a wear-resistant grade, proper mold design and gating are recommended to optimize the orientation of wear-resistant additives for best tribological performance.

Hostaform C 9021 AW POM-C FAQ
Q1: What does “AW” mean in Hostaform C 9021 AW?
A: “AW” stands for Abrasion Wear. This grade is specially formulated to provide enhanced wear resistance and low friction for moving parts and sliding applications.
Q2: What is the coefficient of friction for Hostaform C 9021 AW?
A: The coefficient of friction against steel is typically in the range of 0.15 – 0.25. Please note that actual values can vary depending on surface finish, load, sliding speed, and temperature.
Q3: How does Hostaform C 9021 AW compare to standard POM-C in wear performance?
A: The AW grade offers significantly better abrasion resistance and lower wear rates compared to standard POM-C, making it the preferred choice for applications where long-term sliding or dynamic movement is required.
Q4: Does this material require external lubrication?
A: In most applications, no external lubrication is needed due to the self-lubricating properties of the material. However, in very high load or high-speed applications, supplementary lubrication may be beneficial.
