Ashless Dispersants
China supplier CheMost Additive provide a ashless dispersant is one of the lubricant additive, which is the polyisobutylene succinimide (pibsi), it is ash-free.
What are the ashless dispersants?
Ashless dispersant is one of the lubricant additive, which is the polyisobutylene succinimide (PIBSI), it is ash-free.
Ashless dispersants emerged in the last century due to the widespread adoption of automobiles and the rapid development of the modern automotive industry, which led to improvements in the quality of lubricants and the use of dispersants.
Ashless dispersant works by inhibiting the accumulation of impurities such as sludge in lubricating oil and adsorbing and dissolving these impurities in the lubricating oil, thus maintaining the long-term use of the lubricants .

The molecular structure of ashless dispersant oil
Ashless dispersant oil are generally high-molecular-weight surfactants, and their molecular structure typically consists of three parts: a lipophilic group, a polar group, and a linker group.
- Polyisobutylene succinimide is one type of dispersants, synthesized from highly reactive polyisobutylene and maleic anhydride at high temperatures to form pibsa, which is then combined with polyamines to form polyisobutylene succinimide, abbreviated as pibsi.
- As a dispersant in internal combustion oils to disperse gums, impurities, and sludge in lubricating oils, and also enhance solubility.
- Its key characteristic is that it produces no ash after high-temperature combustion and possesses a certain alkalinity to neutralize acids, thus maintaining the cleanliness of the engine interior.
Types of ashless dispersants:
-
Polyisobutylene succinimide
-
Polyisobutylene mono succinimide
-
Polyisobutylene bis succinimide
-
High molecular weight polyisobutylene succinimide
- Boronated polyisobutylene succinimide
