Product Description

Product Description

T7600 is an HSD Viscosity Index Improver (HSD VII). It has an excellent Shear Stability Index (SSI) and can effectively increase the lubricant oils' viscosity index and depress the pour point to improve the lubricants' low-temperature performance.

Countertype of: Infineum SV260

Application

Example (1)
Add 10wt% dry rubber in Hengli 150N base oil (KV@100ºC=5.0mm2/s), and the kinematic viscosity of the liquid rubber obtained by thermal dissolution is 1000~1400 mm2/s. Dissolve 10% liquid rubber in constant force 150N base oil, and the performance data of the test oil sample are as follows:
Performance in 150N Base Oil

Item	Test Result	Test Method/Standard
KV@100ºC, mm2/s	12.05	GB/T 265
Thickening Capacity, mm2/s	7.0	SH/T 0622 Appendix A

CCS@-30ºC, cP	4070	GB/T 6538-2010
MRV@-35ºC, cP	27700	NB/SH/T 0562-2013

Formulated with 0.5% PPD.
The thickening performance and low temperature performance of T7600 and commercially available OCP (SSI<25) in Group II (or Group III) base oil are compared as follows:
