Sinopec Seps 4030 Improver for Lubricating Oil Viscosity Index (CAS No. 68648-89-5)

Product Description

Product Description
Baling Petrochemical SEPS series product is hydrogenated styrene - isoprene block copolymer in the form of white porous granule or powder. It is mainly used in the lubricating oil viscosity improver, fiber filling gel, elastomer products and plastics modification. On the aspect of lubricating oil viscosity improvement, it has features of thickening, low-temperature, and viscosity - temperature performance, shear stability, anti-oxidation stability, etc, suitable for blending of long-span lubricating oil, low dissolving temperature and fast dissolving rate when blending the lubricating oil.

SEPS Application
In the application of improver for lubricating oil viscosity index, YH-4030 can improve the viscosity - temperature performance of lubricating oil, increase its viscosity index, and make it have strong thickening ability, good low-temperature performance, and good shear stability. It can meet the requirements of multi-grade internal combustion engine oil, particularly the long-span multi-grade internal combustion engine oil, and is a high-grade improver for lubricating oil viscosity index. It is sold in the form of powder or fluffy granule, with low dissolving temperature and fast dissolving rate when blending the lubricating oil. Performance after YH- 4030 is Mixed with Hydrogenated White Oil ( Typical Value, with No Limitation)
