synthetic lithium grease is an all-purpose lubricant that can be used in high temperatures and can resist water. It is a very thick grease, so it can penetrate the crevices of metal parts and lubricate them effectively. However, it is important to remember that it can react with rubber components, which may cause them to swell or degrade. Therefore, it is best to use this type of lubricant only in environments where the temperature will not rise too high.
Lithium grease is based on mineral or synthetic base oil and has additives like anti-corrosion, rust inhibitors, etc. The most common base oil is mineral group I, but it can also be a blend of mineral and synthetic oils. Generally, the chemical formula of simple soap lithium greases is derived from 12HSA (Lithium 12-hydroxystearate) and HCO (hydrogenated castor oil). Lithium greases are probably the most widely used multipurpose greases in the world. They are highly water resistant and have a 130degC continuous operating temperature, a 190-200degC drop point, superior mechanical or shear stability and good storage stability.
White lithium grease has a petroleum base, so it is not recommended for use near rubber components or in humid conditions. It is also not a suitable choice for very cold climates because it has a low melting point and will solidify. This lubricant adheres well to metal and is non-corrosive, but it can attract dust and dirt. It is not as effective as graphite or silicone grease, but it is perfect for basic tasks such as lubricating door hinges.
