| ETHYLENE-PROPYLENE COPOLYMER T613 　 　 SYMBOL: T613 Adopting abroad importing high-quality ethylene–propylene rubber raw materials, in certain proportion abundant to dissolve of HVI150 while being hot, and then by quality device high pressure degrade and make. The products have fine shear stabilities, good thick increasing ability, hot stability and low-temperature performance at the same time, suitable for mid-grade internal-combustion engine oil to suitable for cutting strength. Make forms and list the probably necessary T613 joining amount while adjusting the multistage oil of grade of various kinds of viscosity. SPECIFICATIONS oil degree additives% Basic oil Kinetic viscosity 5W／30 6.5-8.5 3.5--4.5 10W／30 5.5-7.5 5.0--5.5 10W／40 7.5-9.5 4.0--5.0 15W／40 6.5-8.5 6.0--7.0 Items Limits Typical number Test Methods Kinetic Viscosity, 100℃, mm2/s 1300 842 GB/T265 Thickening performance ≮5.2 5.58 SH/T0556 Rate of descent of ultrasonic shear viscidity ≯30 29 SH/T0505 Chroma number ≯2.0 trial GB/T6540 Water,% ≯0.05 1.5 GB/T260 Mechanical impurities,% ≯0.08 0.042 GB/T511 PACKAGE,STORAGE AND TRANSPORATION While using this product as the viscidity index improver concocting the multistage internal-combustion engine oil, temperature should not exceed 120℃.Storing this product for a long time, temperature should not exceed 70℃.
