Nonyl diphenylamine is a pale yellow to yellow liquid that is commonly used as an antioxidant in lubricants, fuels, gasoline, and rubber products. It is also used as an additive in plastics, coatings, and waxes. Nonyl diphenylamine is effective in stabilizing oxygen, light and heat-sensitive products and it helps protect them from oxidative degradation.
Nonyl Diphenylamine is a kind of high temperature amine antioxidant with superior performance,
which has good thermal stability, high temperature conditions, anti-oxidation performance, excellent antioxidant durability, oil-soluble and good compatibility with other additives .
It has synergistic effect together with other antioxidants , especially with the phenolic ester antioxidant compound .
The optimized ratio and control for different alkyl substituents are different with the lower free amine content.
It can be widely used in a variety of high-grade internal combustion engine lubricants, thermal oil, high temperature chain oil, hydraulic oil, compressor oil, turbine oil and other industrial lubricants and a variety of grease and fuel oil.
Polyisobutylene succinimide is a type of dispersant additive that is commonly used in lubricants. It is made by reacting polyisobutylene (PIB) with maleic anhydride, followed by a reaction with an amine compound to form the succinimide structure.
Polyisobutylene succinimide is used to improve the dispersibility of contaminants in lubricants, such as soot, sludge, and varnish. It helps to keep these contaminants in suspension and prevent them from settling and forming deposits.
In addition to its dispersing properties, polyisobutylene succinimide also acts as a detergent and anti-oxidant. It helps to clean and remove existing deposits in the engine and prevents the formation of new deposits. This promotes better lubrication and reduces the potential for engine wear and friction.
Polyisobutylene succinimide is commonly used in engine oils, transmission fluids, hydraulic fluids, and industrial lubricants. It is particularly effective in high-temperature applications, where it can help to prevent the degradation of the lubricant and maintain its performance.
Overall, polyisobutylene succinimide is a versatile additive that provides dispersing, detergent, and anti-oxidant properties to lubricants. It helps to keep engines and equipment clean, reduce friction and wear, and improve the overall performance and lifespan of the lubricant.
