Product Details

Product introduction

The performance of this product is much higher than the traditional viscosity index improver, and it is widely used. This product is a highly refined hydrogenated base oil suitable for the preparation of various oils. The implementation standard is: Q/CRY26-2017


Viscosity index improver glue evaluation

according to SH/T0622-2007 Standard, evaluate the glue liquid.


Plan 1

In Dalian HVI150 base oil, add 10%(mass fraction)KFD6600(T616), Heat up to 60 ~70 .

Plan 2

Use gasoline oil compound agent, a certain proportion of hydrogenated base oil and synthetic base oil. Viscosity index improver T616 modulation  modulate SN 5W-40 and SN 0W-40. The kinematic viscosity, pour point and apparent viscosity of the oil were measured.
