L-HS10 / 15 / 22 / 32 / 46

ISO VG 10–46 Ultra-Low Temperature Wear resistance Shear resistance Wide Temperature Range

Features excellent viscosity-temperature performance and wear resistance, along with demulsibility, foam resistance, and shear stability, suitable for hydraulic systems in low-temperature and complex conditions.

Ultra-Low Temperature Performance Stable operation in extreme cold environments
Anti-wear Extends equipment service life
Demulsibility Effectively reduces system contamination
Shear resistance Excellent Viscosity Retention

Product Description

Product Performance: Excellent viscosity-temperature characteristics and low-temperature performance ensure smoother operation of hydraulic systems in cold conditions. Superior wear resistance, oxidation stability, and corrosion and rust protection reduce equipment wear and extend service life. Outstanding demulsibility, foam resistance, and filterability effectively minimize hydraulic system contamination. Excellent shear stability maintains oil viscosity under severe operating conditions. Enhanced compatibility with various conventional sealing materials. Application Scope: Suitable for medium and high-pressure hydraulic systems in engineering, construction, mining, oil fields, steel rolling, plastic processing machinery, as well as marine and vehicle equipment operating in severely cold winter regions with large temperature fluctuations; also applicable to medium-load industrial gear transmissions.

  • Excellent viscosity-temperature performance ensures smoother hydraulic system operation at low temperatures
