These extreme-pressure additives generally contain sulfur, phosphorus, chlorine, and other elements. These elements will form molecular films of compounds such as iron sulfide, iron chloride, and iron

A General Introduction to Anti-Rust Additives, the Classification of anti-rust additives, Generally, according to the characteristics of the solution, Rust Preventives can be divided into water-solubl

Lubricant additives code in China, the lube additives are divided into detergents and dispersants, antioxidant and anticorrosion additives, oily agents and friction modifiers, extreme pressure & antiw

In lubricant blending, in order to eliminate (inhibit) bubbles or foam, it is often necessary to add a certain amount of additives. These chemicals that can inhibit or eliminate foam are called Antifo

CCS measures the engine oil's low-temperature (-30°C), high-shear viscosity. Too high a CCS value causes difficult cold starts or severe engine wear due to poor oil flow when thick.

A Four Ball Lubricant Tester is a type of instrument used to determine the load-carrying lubricating properties of different oils, greases, and other lubricating fluids.

High-Temperature High Shear (HTHS), this parameter is the apparent viscosity of the lubricant fluid tested by the capillary viscosity tester at 150°C.

Lubricating oil will inevitably come into contact with metal during use, and will be oxidized under the action of light and heat.

KRL is a method to test the Shear Stability of polymer-containing fluids (Usually refers to lubricant oil containing Viscosity Index Improver). The test method measures the percent viscosity loss of l

A simple introduction to the lubricant additive- PMA viscosity improver, Polymethacrylate (PMA) Viscosity Index Modifier, how it is produced, and how it performs.

Shear stability is a polymer's ability to resist shear stress and is a key performance indicator for Viscosity Index Improvers (VIIs). Poor shear stability causes the polymer's main chain to break und

The total base number (TBN) is an index for determining effective additive components in engine oil. Total base number (TBN) refers to the content of basic additives in lubricant, which is an importan
