Lubricants for Performance Improvement

For specific performance improvements, typical lubricating additives such as graphite, molybdenum disulphide, PTFE, polyethylene (and even lubricating oil 

Lubricants may be internal (incorporated into the host resin during production or compounding) or external (placed between the sliding surfaces before or during operation). Addition of PTFE to host polymers such as polyamide, polyacetal, polyphenylene sulphide, and PETP polyester considerably reduces their friction coefficients. Internal lubrication is not always the answer, however. In some cases (such as polyamide with 2 wt% silicone oil sliding against steel at a moderate speed and a low load), internal lubrication has been observed actually to increase friction.
