Information

Cheapest High Active Polyisobutene is becoming more and more well-known. Through research, it has been found that low-molecular-weight polyisobutene can improve the lubricating performance of lubricating oil, reduce the formation of carbon deposits, reduce equipment energy consumption, and prolong service life.
(1) Shear stability of low molecular weight polyisobutylene
Low-molecular-weight polyisobutylene, which is widely used, generally refers to low-molecular-weight polyisobutylene with a molecular weight of 600-2400. In the actual use process, using 1300/2400 thickened No. 460 synthetic hydrocarbon industrial gear oil to run on the grinding roller shaft of the medium-speed coal mill in the mine for one year, the viscosity change is not obvious. The 80W/90GL-5 gear oil formulated with 1300 can pass the bench test, while the vehicle gear oil thickened with 2400 has a significant change in viscosity after one year of operation. Therefore, 2400, which can be used in industrial gear oil, should be used with caution in automotive gear oil, at least the amount should be controlled.

(2) Oxidative detergency and carbon deposition tendency of low molecular weight polyisobutylene
As the molecular weight increases, the detergency of low molecular weight polyisobutylene becomes worse. Low-molecular-weight polyisobutylene decomposes into free radical monomers at high temperature, which can be fully burned during the lubrication process of two-stroke engines, with low smoke emission, light carbon deposition, and loose paint film. Two-stroke oils that do not use low-molecular-weight polyisobutylene perform poorly in this regard. In neutral oil, bright stock and synthetic oil, the effect of low molecular weight polyisobutylene on reducing carbon deposition is consistent.
(3) Friction properties of low molecular weight polyisobutylene
As the molecular weight of low molecular polyisobutylene increases, the wear track decreases, which is caused by the difference in oil film thickness due to the difference in oil viscosity.
