Product Description

Hydrogenated Styrene Diene Copolymer HSD Type Viscosity Index Improver 

Introduction of HSD
HSD is a viscosity index improver for hydrostyrene-vinyl diene copolymer HSD type. HSD in the application of lubricating oil viscosity index improver can improve the viscosity and temperature performance of lubricating oil, improve its viscosity index, strong thickening ability, good low-temperature performance, especially good shear stability, can meet the requirements of multistage internal combustion engine oil, especially the preparation of large-span multistage internal combustion engine oil, is a high-grade lubricating oil viscosity index improver. The product is sold in powder or fluffy particles, and the solution temperature is low and the dissolution speed is fast.
