Types Of Lubricants And Their Features

There are various types of lubricants available at lubricant companies in UAE: Molybdenum disulfide, Oil-based lubricants, Synthetic polymers, and synthetic fluids. These substances are used in various applications such as motor oil. Read on to find out more. Here is a brief overview of each type. You’ll learn about the various benefits of each type and how to select them for your application.

Molybdenum disulfide:

As the name suggests, molybdenum disulfide is an inorganic compound with the formula MoS2. It occurs naturally as the mineral molybdenite, and its lubricating properties are based on the formation of metal-sulfur bonds. When the metal is under pressure, these bonds are continually broken and reformed, forming a thin film that reduces friction.

It is used in a variety of lubricants, including engine oils and greases for bits. Synthetic greases are typically made from a mixture of molybdenum disulfide and metal soaps. A synthetic lubricant should have a viscosity of 600-750 cP at 120 degC. Rock bit bearings require a viscosity of at least 200 cP at 100 degC. Other heavy-duty greases contain calcium fluoride or metal soaps as thickeners.

Oil-based lubricants:

The most common oil-based lubricants are mineral oils. They typically consist of several hydrocarbon species, with average molecular weights of 300 to 600. Most contain paraffin, naphthenes, and saturated long-chain hydrocarbons, with aromatic components, in smaller amounts, present in some oils. Many other constituents are also present in lesser amounts, such as hydrogen sulfide and hexane.

Synthetic polymers:

There are six main types of lubricants: naturally occurring, synthetic, and blended. Natural polymers include tar, tortoiseshell, and animal horn, and synthetic polymers include polyethylene, styrene, and vinyl chloride. Polymers are made from carbon, hydrogen, and sometimes other elements, such as fluorine and silicon. These materials are strong, noncombustible, and have a variety of applications.

Synthetic polymers are often used for biomedical and pharmaceutical applications. Some of the most commonly used types of synthetic polymers include poly (ethylene glycol), poly (propylene glycol), poly (vinyl acetate), and polystyrene. Other examples include polyurethane and polymaleic anhydride. Each has its own set of benefits, but they all share similar characteristics. When you are looking to buy lubricants, this guide will help you make informed decision.
