Graphite has traditionally been used to improve self-lubricating properties.
Molybdenum disulfide and the like have been added to polymeric substances, but although this reduces sliding resistance, it also reduces wear resistance and workability. especially,
When used under oil-lubricated conditions such as oil seals, there is a tendency for physical properties to deteriorate and wear to increase significantly due to swelling due to oil impregnation.
