Sliding of two materials under weight against each other leads to wear. Devices containing sliding materials such as rotating shafts, rolling bearings and washers have wear. Wear resistance can be measured by determining the material loss in different environments by varying temperature, load, surface roughness and speed. There is a plastic wear resistance chart that ranks materials out of 20 the best wear resistant plastic. Plastics are used in gears, high performance bearings, washers, seal rings and slides. For this they must be able to withstand wear, high temperature, aggressive chemicals and load in both lubricated and dry environments.

There is new range of wear resistant plastics available in market that provides you the proper combination of tribological and mechanical properties. Along with chemical resistance and inherent heat, they are the best alternative to the metal in wear applications and high temperature friction. Their unique features that make them best are:

• Lubricated and dry environment
• Long term use from 125-270°C
• Short term use up to 270°C
• Less noise and light in weight
• Self lubricating for long life
• Non-galling and non corrosive.

Wear resistant plastics are good substitute of the stainless steel. They are widely used in the coating of aerospace equipments and in many injection tools.
