This paper makes an approach to density of EP Lithium-base grease and finds several related factors, which play a role in production.

The soap fiber of the said grease is similar to that of the compounded lithium base grease, the former is cheaper and its water resistance and anti wear properties are improved.

Lithium-calcium base grease, prepared by adding calcium soap into lithium base grease, can retain the multifunction of lithium base grease, reduce tie oast and improve the water resistance property.
