Solid lubricants are solid substances used to prevent damage to a pair of material surfaces that are in contact and in relative motion with each other or reduce their wear and friction.
They are effective at locations subject to high temperatures or heavy loads beyond the working range of oils and those where oils cannot be used.

【Characteristics of Typical Solid Lubricants】

Name	Appearance	Density	Coefficient of Friction	Load Carrying Capacity	Heat Resistance	Advantages
Molybdenum Disulfide		4.8g/cm3	0.04	784MPa	350℃	Low friction is achieved as a layered crystal structure shears along layer boundaries.
Graphite		2.2g/cm3	0.06	490MPa	550℃
Organo Molybdenum Compounds		-	-	-	-	Organo-molybdenum compounds forms molybdenum disulfide-like film on metal surfaces as a result of friction heat.
PTFE		2.2g/cm3	0.04	196MPa	300℃	A low-friction fluoride. Particularly effective in plastics lubrication.
Copper		8.96g/cm3	-	-	1083 ℃	A soft metal used as an anti-seizure agent in the ultra-high temperature region.
