Bartran™ HV high viscosity index (VI) lubricants are based on a carefully selected ashless additive system designed to meet and exceed the most exacting performance standards.
Bartran HV oils are intended for severely stressed hydraulic systems requiring a high level of anti-wear performance and fine filtration. In addition, Bartran HV exhibits excellent corrosion protection as well as outstanding thermal and oxidative stability. Bartran HV has excellent hydrolytic stability and separates rapidly from water contamination. The selection of a shear stable VI Improver ensures that there is no excessive loss in viscosity due to mechanical shearing. The VI Improver also imparts a very low pour point which enables the product to be used in very cold environments.
These grades are intended for two main types of duty:
The Bartran HV range is fully compatible with elastomer materials commonly used for static and dynamic seals, such as nitrile, silicone and fluorinated (e.g. Viton) polymers.
