What are some materials with low friction?

Due to its low coefficient of friction, PTFE (polytetrafluoroethylene) is often used for sliding applications. In addition to PTFE, the classic bearing and wear materials made of polyimide, PEEK, PPS, Nylon, Acetal and Polyester are also known for their good sliding friction properties.

What plastic has the lowest friction factor?

PTFE
PTFE has the lowest recorded m value for any material with a dynamic coefficient of friction of between 0.05 and 0.15 and a static coefficient of friction of approximately 0.05. The other fluorocarbons i.e. FEP , PFA, ETFE and ECTFE all have extremely low coefficients of friction in the region of 0.14 to 0.25.

Why friction and wear are not a material property?

We can say that coefficient of friction and wear are not the material properties but they are the responses of tribo-sysytem. Wear is defined as a set of adhesion, transfer, abrasion, fatigue and oxidation. Due to these processes transfer of matter takes place from one state to another.

What is low friction surface?

Low friction coatings are popular types of industrial coatings used today. These coatings are named so due to their low coefficient of friction. There are various types of low coefficient of friction coatings such as PTFE, Molybdenum Disulfide, Tungsten Disulfide, etc.

Which is an example of a low friction material?

PEEK, UHMW, Acetal, and pDCPD are all good examples of ‘hard wearing,’ abrasion resistant plastics with low-friction that can be used in applications that require high performance and superior mechanical properties. PEEK is a thermoplastic known for its naturally low-friction material, and well-rounded abrasive and fatigue wear resistance.

Why are plastics good for friction, wear and bearings?

Generally, plastics are very good wear materials with a low coefficient of friction, making them ideal for applications where friction is a consideration. In addition, the abrasion resistance of most plastics is also high under dry running conditions. In applications such as bearings, where one part slides over another, wear is often severe.

What kind of plastic is low friction and corrosion resistant?

Polydicyclopentadiene, or simply pDCPD, is a liquid plastic raw material with excellent abrasion resistance and low-friction. This thermoset resin has elasticity and is lightweight, but is also extremely impact and corrosion resistant.

How does low friction plastic help the environment?

Finding new applications for low friction plastic could make a significant contribution toward reducing global fuel utilization, and reducing CO2 emissions.
