Lubricating Greases By Petro Global

we are engaged in supplying and trading of lubricating greases in Mumbai, Maharashtra, India. Good lubricating greases were not available until the development of petroleum-based oils in the late 1800's. Today, there are many different types of lubricating greases, but the basic structure of these greases is similar.

In general, grease consists of a thickening agent dispersed throughout lubricating oil. The thickening agents or gallants include alkali metal soaps, clays, polymers, carbon black, colloidal silica and aluminum complexes. The lubricating oil may be petroleum oil or synthetic oil. The most common type of grease is the soap-based grease. The soap comes from animal or vegetable fats or fatty acids, wool grease, rosin or petroleum acids. The lubricating oil is commonly mineral oil from paraffinic, naphthenic or aromatic hydrocarbons. Other components of these greases include unreacted fat, fatty acids and alkali, unsaponifiable matter (including glycerol), rosin or wool grease and water. Some of the other additives used in grease are oxidation inhibitors, rust and corrosion inhibitors, color stabilizers, metal passivators, water repellants and viscosity index improvers.
