EP Lubricant

Short Description:

This product is based on mineral oil and vegetable oil, supplemented by extreme pressure additives containing S, B, N, etc., and surfactant. It is used to improve extreme pressure lubrication performance of high-density drilling fluid under high temperature and high salt content. The molecules contain strong adsorption groups and extremely high content of pressure elements, which can form chemical adsorption films with high strength and toughness on borehole walls and drilling tools, and contain strong hydrating groups with excellent salt resistance.
