Ashless Dispersants
Ashless dispersants (pibsi dispersants) are lubricant additives of the polyisobutylene succinimide (PIBSI), china manufacturers custom.
Ashless dispersants (pibsi dispersants) are lubricant additives of the polyisobutylene succinimide (PIBSI), it is ash-free.
- Polyisobutylene succinimide is synthesized from highly reactive polyisobutylene (PIB) and maleic anhydride (MA) at high temperatures to form PIBSA, which is then combined with polyamines to form Polyisobutylene succinimide, abbreviated as PIBSI. It can be used as a dispersant in internal combustion engine oils to disperse gums, impurities, and sludge in lubricating oils. 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.
By reacting polyisobutylene through a thermal process and then undergoing amidation, It can disperse impurities such as oil sludge, paint film, and soot, and also enhance solubility.
Types include:
- polyisobutylene bi-succinimide
- polyisobutylene succinimide
- polyisobutylene mono succinimide
- polyisobutylene bis succinimide
