YBS-8231 Extra High Temperature Grease is a high-temperature, heavy-duty industrial equipment grease. This product uses imported composite lithium- based thickener and is specially formulated with high-viscosity fully synthetic base oil and selected imported high -temperature resistant solid lubricant additives such as boron nitride and molybdenum disulfide. It provides excellent wear-resistant lubrication protection in heavy-load, low-speed, water-rich, and high-temperature environments.
Performance characteristics
High viscosity base oil: The excellent oil film composition of the base oil gives the grease higher anti-friction and anti-wear properties.
Excellent high temperature resistance: over 300℃ gives the grease extremely high heat resistance. In environments above 330℃ , the base oil evaporates more, and solid lubricants such as boron nitride, molybdenum disulfide, or graphite and thickeners play their role, ensuring long-term operation of the equipment.
Excellent water resistance and stability: It provides continuous protection even in the presence of large amounts of water and water vapor.
Excellent mechanical shearing properties: Its unique mechanical shear stability allows the grease to remain in the lubricated area for a long period of time without softening or leakage.
Excellent corrosion protection performance: provide excellent rust protection in water-saturated environments with long relubrication intervals.
Enhanced extreme pressure and anti-wear properties: exceptional extreme pressure and anti-wear protection without the addition of any extreme pressure or anti-wear additives.
