Product Description
Product Details
Introduction
This product is made of highly active polyisobutylene and is produced by a thermal addition process. It has excellent thermal stability and cleanliness; good low-temperature sludge dispersibility; can inhibit the formation of carbon deposits and paint films on engine pistons; and its high-temperature cleanliness and high-temperature resistance are far superior to traditional T 154 and T 155 products.
Product features
Excellent high-temperature resistance
Good low-temperature dispersibility
Good oil solubility
Good solubilization effect
