KFD6600(T616) is a new viscosity index improver for ethylene propylene rubber. This product is made of deep refined hydrogenated base oil, which is subjected to thermal dissolution and catalytic high temperature degradation, and then degraded by high pressure of homogenizer and treated by two filtration processes. This product has excellent low temperature cold start performance and excellent shear stability as well as excellent high temperature and high shear performance.
Suitable for the modulation of various oils:
lHigh-grade internal combustion engine oil
lAutomatic transmission fluid
Executive Standard: Q/CRY26-2017
Evaluation of Viscosity Index Improver Glue：
The glue evaluation was carried out in accordance with the SH/T0622-2007 standard.
In Dalian HVI150 base oil, add 10% (mass fraction) T616, heat to 60 ° C ~ 70 ° C, stir to obtain a sample, the oil sample shear stability index (diesel nozzle method), thickening capacity and other performance parameters Determination.
The main physical and chemical indicators of T616 viscosity index improver are shown in Table 1.
