Oil IGP-38 (TOR 38.101413-97) is distillate oil, residual oil or a mix of distillate and residual oil oils from sulfurous petroleums of deep selective clearing with antioxidizing, wear-protective, anticorrosive and antifoam additives.
The oil usually is used for greasing of the modern domestic and import equipment in various branches of a national economy for which operation oils with the improved operational properties are necessary. Oil IGP-38 serves as a working liquid in hydraulic systems of machine tools, automatic transfer lines, presses.
Use this oil for greasing of high-speed transmissions, variable-speed transmissions, electromagnetic and gear couplings, bearing sites, plain slide ways and roller guide way and in other sites and mechanisms where oils with the improved antioxidizing and wear protective properties are required. The basic indicators characterizing operational properties of oils IGP are viscosity, stability against oxidation, anticorrosive properties and firmness to foaming.

Density at 20°С, kg/cu.m, not more than: 890
Kinematic viscosity, cSt, at 40 °С, not less than: 55-65
Mass fraction of zinc, %, not less than: 0.04
Mass fraction of sulfur, %, not less than: 1
Flash temperature, in an open cup, °C, not lower than: 210
Hardening temperature, °C, not above:-15

Data on operational temperatures represent values, which are guided by a structure of lubricants, and also on a scope and technology of use. Depending on a kind of mechanical-dynamic loading lubricants change the consistence, conditional viscosity or viscosity at various temperatures, pressure and duration of operation. These changes of indicators can affect work of components.
