High Cost-effectiveness Star Polymer Viscosity modifiers from China
Chorus can provide high performance HSD viscosity improvers to balance thickening ability and shear stability. Widely used in large-span multi-grade internal combustion engine oil, meeting the requirements of maintaining viscosity at high temperature and pumping at low temperature.
- Star Polymer Viscosity Modifiers T7600 has the sheer stability of 11, which is useful to maintain the viscosity and is used in multi-grade internal combustion engine oils.
-
Hydrostyrene‐vinyl Diene Copolymer HSD Viscosity Index Improver T7700 has a high thickening ability, high-temperature oxidation resistance and excellent shear stability, which can satisfy the requirements of multi-grade internal combustion engine oils.
Why use HSD viscosity improvers?
Hydrogenated styrene diene copolymer (HSD) has excellent sheer stability.
HSD Viscosity Index Improver has good low-temperature performance for base oil.
Basic Characteristics and Principles of Viscosity Improver
Viscosity improver is a high molecular oil-soluble material, added into base oil to form high polymer solubility, which can increase the viscosity of base oil and meet the different requirements of lubricating oils, not being too thin at high temperature and not being too sticky at low temperature.
A viscosity thickener can not only thicken the base oil and improve the viscosity-temperature performance, but also change the dynamic viscosity at low temperatures.
Structure Advantages Of HSD Viscosity Index Improver (Star-Shape Vs. Linear Chain)
Compared with linear chain HSD viscosity index improver, star-type hydrogenated styrene diene copolymer (HSD) has a better thickening ability and higher shear stability.
Molecular Structure Characteristics of HSD Viscosity Modifier
HSD is a block copolymer of styrene, butadiene, or isoprene, which has a star-shaped or linear structure.
Among them, HSD, as a viscosity index improver, has a multi-arm structure, with good performance of shear stability and thickening ability.
Core Performance of HSD Viscosity Index Improver
Hydrogenated styrene diene copolymer(HSD) has excellent shear stability, thickening ability and thermal stability. What's more, HSD viscosity index improver has a low negative impact on the low temperature performance of base oil and can satisfy the needs of multi-grade internal combustion engine oils. HSD viscosity index improvers are often used in high-grade lubricating oil and are one of the main viscosity modifiers.
