Excellent Thickening Ability Viscosity Index Improver KFD6600(T616）
KFD6600 (T616) is a new type of viscosity index improver developed by Shenyang Great Wall Lubricant Manufacturing Co., Ltd. The products are sold well in domestic and foreign markets and have excellent thickening ability. Not only does it blend well with oils, but it also reduces your oil blends and is your best choice.Chat Now
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.
In Dalian HVI150 base oil, add 10%(mass fraction)KFD6600(T616), Heat up to 60 ℃ ~70 ℃.
