What are additives in lubricants?

Conventional Lubricant Additives

  • Anti-oxidants. Oxidation is the general attack of the weakest components of the base oil by oxygen in the air.
  • Rust and Corrosion Inhibitors.
  • Viscosity Index Improvers.
  • Anti-wear (AW) Agents.
  • Extreme Pressure (EP) Additives.
  • Detergents.
  • Dispersants.
  • Anti-foaming Agents.

Why additives are added to polymer?

Additives are chemicals added to the base polymer to improve processability, prolong the life span, and/or achieve the desired physical or chemical properties in the final product. While the content of additives is typically only a few percent, their impact on polymer performance and stability is significant.

Which polymer is added to improve viscosity?

The copolymer used is ethylene propylene diene monomer (EPDM). The oil viscosity index (VI) and viscosity/temperature characteristics were improved at different concentrations 2468 and 10% by weight solutions.

What is the role of polymer in engine oil?

One important application for polymers is in crankcase lubricants, in which various specialty polymers and copolymers are used as viscosity modifiers, dispersants, and pour-point depressants. These polymers give an oil all-season properties and are the most effective additives in producing multigrade oils.

What are 3 oil additives?

Additives Included In Motor Oil

  • Viscosity Index Improvers.
  • Detergents.
  • Corrosion Inhibitors.
  • Antioxidants.
  • Additional additives.

What additives are in synthetic oil?

The most common esters used for synthetic motor oil are diesters and polyol esters. Diesters are commonly used as an additive with PAO base stock oil.

What are polymer additives?

The most common polymer additives are stabilizers, plasticizers, lubricants and flame retardants. Stabilizers are added to prolong the useful life of a polymer formulation by protecting it from thermal and light-assisted oxidation.

What are additives used for?

Substances that are added to food to maintain or improve the safety, freshness, taste, texture, or appearance of food are known as food additives. Some food additives have been in use for centuries for preservation – such as salt (in meats such as bacon or dried fish), sugar (in marmalade), or sulfur dioxide (in wine).

What are the various additives added in a polymer?

What is a viscosity improver?

A viscosity index improver is a complex polymer additive that expands at elevated temperatures to thicken the lubricant and ensure a more stable and consistent viscosity. This ensures the lubricant fully protects the equipment at both low and high temperatures.

What are the different types of oil additives?

Here are some of the most common types of additives included in motor oil.

  • Viscosity Index Improvers. Probably the most important additives in motor oil affect the way oil flows through your engine.
  • Detergents.
  • Corrosion Inhibitors.
  • Antioxidants.
  • Additional additives.

What are the different types of lubricants?

There are three main types of lubricants: oil-based, water-based, and silicone-based. The best lubricant for women depends on their needs.
