Viscosity Index Improver (T614)
SYMBOL: T614
T614 is adopted high-quality importing ethylene–propylene rubber raw materials dissolving in hot HVI150 in certain proportion and then degrading by homogenizer in high pressure. The products have fine shear stabilities, good increasing thick ability, hot stability and low-temperature performance, suitable for modulating high and middle grade internal-combustion engine oil of various kinds of viscidity. Make forms and list the probably necessary T614 joining amount while adjusting the multistage oil of grade of various kinds of viscidity. For concocting multi-level oil of various degrees of viscosity ,the addition amount is shown in table below
