Abstract :

Polytetrafluoroethylene (PTFE) is currently finding increasing utility due to its unique properties like high chemical resistivity, self-lubricating and high temperature stability. When rubbed or slide against a hard surface, PTFE exhibits a low coefficient of friction but a high rate of wear. These unique properties of the polymer have encouraged many mechanistic and physical examinations of the processes involved in the friction and wear of this polymer. However, PTFE exhibits poor wear resistance, especially abrasion. The wear resistance of PTFE can be significantly improved by addition of suitable reinforcement materials.
