Hydro styrene-vinyl diene copolymer (HSD) can improve the lubricant's viscosity and temperature performance, improve its viscosity index, it has a strong thickening ability, good low-temperature performance, especially good shear stability, can meet the requirements of multi-class internal combustion engine oil, especially for blending of large-span multistage internal combustion engine oil, is a high-grade lubricant viscosity index improver.
This HSD viscosity index improver has a good thickening ability, high-temperature oxidation resistance, shear resistance, and the ability to improve the low-temperature performance of lubricant oil.
This HSD VII is in the form of powder or fluffy blocks, it has a low solution temperature, and the dissolution speed is fast.
