The YB-T615 VII (Viscosity Index Improver) is an ethylene-propylene copolymer. Lubricant Component Additives is used in lubricants and oils to improve their viscosity index, which is a measure of the oil's resistance to changes in viscosity with temperature.
Ethylene-propylene copolymers are synthetic elastomers made by the polymerization of ethylene and propylene monomers. These copolymers have excellent thermal stability, oxidation resistance, and low-temperature properties. They are commonly used in automotive lubricants, Industrial Lubricating Oils, and hydraulic fluids.
By adding the YB-T615 VII to lubricants and oils, the viscosity index is increased. This means that the oil will maintain its viscosity over a wider temperature range, providing better lubrication and protection for various mechanical components. The ethylene-propylene copolymer acts as a thickening agent, reducing the tendency of the oil to thin out at high temperatures and preventing it from becoming too thick at low temperatures.
Overall, the YB-T615 VII viscosity index improver, which is an ethylene-propylene copolymer, enhances the performance of lubricants and oils by improving their viscosity index and ensuring optimal lubrication across a range of temperatures.
