The product is mainly applied in improving and increasing lube oil viscosity. It has a good compatibility with other additives, and it will have no side effect on other index.
(1) Thickening ability: The thickening ability of Ethylene-propylene copolymer viscosity index improver varies with the brands. T-612 has a better thickening ability than other brands
(2) Shearing stability: The performance of shearing stability varies with the volume of molecular weight and its distribution of width. T-614 is superior to T-612?T-613.
(3) Thermal oxidation stability: The product of ethylene-propylene copolymer viscosity index improver shows an excellent thermal oxidation stability with heat-resistance and no decomposition under high temperature conditions.
(4) Low temperature performance: T-614 shows a good performance under low temperature. There is little influence to the low temperature pumping performance of multi-grade lube oils by the single application of T-614, which is better than other brands of additives.
(5) T-612A?T-613A?T-614A are all high-viscosity products which have particular excellent thickening ability; T-615A is also a high-viscosity product, which has better ability in thickening and shearing stability.Information provided by Jilin Xingyun Chemical Co., Ltd. |
