About Synthetic Oils, Greases and Lubricants

Synthetic oils, greases and lubricants are based on compounds that consist of boron nitride (BN), chlorofluorocarbons (CFC), esters, diesters, silicone, polyglycol or mixtures of synthetic fluids and water. Synthetic products are generally more expensive than non-synthetic fluids, but provide better fire resistance and cooling performance. The cost and heat transfer performance of semi-synthetic fluids falls between those of synthetic and soluble oil fluids. Some synthetic oils, greases and lubricants are used as circulating coolants, flood or mist coolants, insulating oils, lapping vehicles, lubricants, heat transfer fluids, or thermal oils. Others are used as grinding, metal working, metal forming, metal cutting, hydraulic, transmission, quenchant, or vacuum fluids. Base oils and additives are also available. High water content fluids (HWCF) and high water base fluids (HWBF) are used in applications where leakage is likely to cause ignition. Solid lubricants or dry film lubricants are designed to reduce friction, binding or wear; exclude water; or provide other specialized characteristics.

Synthetic oils, greases and lubricants vary in terms of thermal conductivity, dielectric strength, specific gravity, kinematic viscosity, viscosity index, usage concentration, operating temperature, boiling point, and flash point. Thermal conductivity is a measure of the ability to transfer heat. Dielectric strength is the maximum voltage field that a material can withstand before electrical breakdown occurs. Specific gravity is density normalized to water or another standard. Kinematic viscosity is the time required for a fixed amount of fluid to flow through a capillary tube under the force of gravity. Units of measure include stoke, centistoke (1/100 of stoke) and Saybolt universal seconds (SUS). The viscosity index is based on two temperature extremes. Usage concentration is a volumetric amount. Operating temperature is a full-required range. Boiling point is the temperature at which synthetic oils, greases and lubricants boil. Flash point is the lowest temperature at which substances produce sufficient vapors to form an ignitable mixture in air near the surface. When selecting fire resistant products, fire point and autogenous ignition (AIT) are additional considerations.

Products & Services Related to Synthetic Oils, Greases and Lubricants

Dielectric Greases and Insulating Fluids
Dielectric greases and insulating fluids are insulating oils, greases, transformer oils and fluids that have a high dielectric strength and are used in transformers, capacitors, EDM machining, and other electrical device applications.
Heat Transfer Fluids and Thermal Oils
Heat transfer fluids, thermal oils, circulating coolants, and heater liquids are used to carry thermal energy in process heating and machine cooling applications.
Hydraulic Oils and Transmission Fluids
Hydraulic oils and transmission fluids are used to transmit power in hydraulic equipment and power transmission applications.
Industrial Greases
Industrial greases are thickened gels that consist of natural, synthetic, or semi-synthetic substances. They do not run off surfaces and are used in a variety of lubrication, sealing, and exclusion applications.
Industrial Lubricants
Industrial lubricants are oils, fluids, greases and other compounds designed to reduce friction, binding or wear and exclude moisture. Specialized characteristics may enhance thermal conduction across thermal interfaces or reduce electrical resistivity across electrical joints.
Metal Working Lubricants, Coolants and Fluids
Metal working lubricants, coolants and fluids are specialized coatings and carriers for metal forming, metal cutting, lapping, polishing, and grinding applications.
Solid and Dry Film Lubricants
Solid and dry film lubricants form a dry layer or coating that excludes moisture and reduces friction, binding, and wear. They often contain additives such as corrosion, oxidation, and rust inhibitors.
