Product Description
Product Details
Introduction
This product is a boronized ashless dispersant produced by thermal addition process with high-activity high molecular weight polyisobutylene as raw material. It has excellent high temperature resistance, good detergency and low-temperature sludge dispersibility, as well as good wear resistance and oxidation resistance, and can inhibit the formation of carbon deposits and paint films on engine pistons.
Product features
Excellent thermal stability
Good low temperature dispersibility
Good oil solubility
Good detergency
Good anti-oxidation and anti-wear effects
The product does not contain chlorine
