Celanese Hostaform C 9021 TF POM+PTFE Description
Hostaform C 9021 TF is a copolymer formaldehyde resin manufactured by Celanese Corporation, also known as “POM-C material.” This material has been modified with polytetrafluoroethylene (PTFE) and offers excellent lubricity and a low coefficient of friction; it is commonly used in the production of sliding modules.
Hostaform C 9021 TF is manufactured in both the United States and Germany. If you have specific requirements regarding the country of origin, please let us know in advance.
As shown in the image on the left, Hostaform C 9021 TF Natural Color consists of white, nearly spherical granules. We also offer Hostaform C 9021 BK, a black POM.
Celanese Hostaform C 9021 TF POM+PTFE Advantage
- Low wear POM, Hostaform C 9021 TF contains a PTFE lubricity enhancer that effectively improves the material’s wear resistance, making it particularly suitable for the manufacture of sliding mechanisms that require low friction.
The image on the left shows a comparison of the wear resistance of polished steel balls versus POM balls.（(v = 100 mm/s / F = 5N / one-direction movement/friction, wear + noise after 1 h)）.
It is evident that the coefficient of friction for Hostaform C 9021 TF is less than 0.2, which is significantly lower than the coefficient of friction of 0.43 for the more commonly used C 9021 POM resin; furthermore, its wear depth is only 8 μm, clearly demonstrating its superior wear resistance.
