In the field of mechanics, grease refers to the pasty and consistent product commonly used as a lubricant. Indeed, it coats an element with an oily substance to reduce its friction and promote its sliding with another element. On the market, there are many variants of greases, including universal greases, vaseline greases, silicone greases, and industrial greases.
Silicone greases, often presented in aerosol form, are generally used in plumbing fixtures and plastic or metal threads, particularly for taps, valves, and metal or plastic seals in the food industry. They can also be used to facilitate the installation of O-rings or flat seals and to protect ball bearings that operate at low speed. There are also industrial greases, which exhibit excellent oxidation resistance and provide good protection against wear and corrosion in a humid atmosphere. Vaseline greases can also be mentioned, made from a mixture of wax and highly refined oils and used in various fields, including construction, foundry, mechanics, and transportation. Finally, there are multi-purpose greases that offer excellent water resistance and good mechanical stability. This type of grease is mainly used in heavy industry and the paper industry.
