Description
HQT-630 is polymethacrylate solution in the deeply refined mineral oils HQTH-630 is high-quality viscosity index improver with high shear stability specially designed for hydraulic fluids.
HQT-630 viscosity index improver has a wide range of applications, which is widely used in various kinds of base oils. It has excellent shear stability, low-temperature performances and strong thickening and index increasing abilities.
HQT-630 has excellent low temperature fluidity, excellent shear stability, and can effectively improve the viscosity index with narrow MW distribution, and It can inhibit the wax crystallization, and it has a good effect on depressing pour points, which has excellent filtering and demulsification performances.
Applications
HQT-630 is mainly used in blending hydraulic oils, specially for the hydraulic oils with low temperature and high viscosity index, as the main component in hydraulic oil formula, which has the double effect of increasing viscosity index and depressing pour points under the condition of guaranteeing the shear stability, HQT-630 can keep the viscosity of hydraulic oils being stable, staying best in the big temperature, and performing well with the highest running efficiency, reducing the energy consumption, protecting the equipment and improving the performances.
