Greases

According to the definition given by ASTM (American Society of Testing Material), a lubricating grease is a solid to semifluid product composed by thickening agent in a liquid lubricant. The most used thickeners are metallic soaps, organic and inorganic thickeners. The base oils used can be: mineral, synthetic, vegetable or esters of natural or synthesis origin. The combination of thickeners, base oils and additives gives to the grease its characteristics, performance and range of use. The National Lubricating Grease Institute (NLGI) has developed a numerical scale to classify the consistency of greases. It defines nine distinct grades of greases, ranging from 000 (extremely fluid) to 7 (solid). Eni offers a very wide range of lubricating greases for all applications in a variety of sectors: heavy industry (cement plants, steel mills), papermaking, factories and marine applications.
