ACLUBE Viscosity Index Improvers (VII) and Pour Point Depressants (PPD)
ACLUBE products provide the necessary viscosity stability required over the wide temperature range experienced in applications from Engine Oil, Transmission Fluid, Hydraulic fluid, and other demanding applications where lubricants provide protection to critical moving parts. We offer a wide range of viscosity index improvers and pour point depressants for lubricating oils under the trade name of ACLUBE as follows (Table1, 2).

ACLUBE VISCOSITY CONTROLLING AGENT
Our high-quality Viscosity Index Improver (VII) provides Improvement of a lubricant’s viscometrical property. Our unique monomer and proprietary monomer blends technology achieve excellent VI with excellent Shear stability (Table 3).
PPD products are suitable for Gr1-3 oil. Our R&D team can support your determination. We are also now focused on lubricant for Electric vehicles.
- High VI with good Shear stability
- VII and PPD for automotive lubricating oil (Driveline, Engine, Gear), Hydraulic fluid, shock absorber and etc.
Table 3 Performance of Viscosity Index Improver
|Kinematic Viscosity* mm2/s||Viscosity Index||SSI** %|
|ACLUBE V-1001||5.35||23.8||170||1.5||Shear stability|
|ACLUBE V-4020||8.59||35.6||232||48.1||Thickening property|
* A mixture of the following base oil and a viscosity index improver (the ratio = 90:10) was evaluated.
Base oil properties: kinematic viscosity (100 °C); 4.31 mm2/s, kinematic viscosity (40°C); 20.3 mm2/s, Viscosity index: 121
The viscosity change with temperature is smaller as the viscosity index value heightens.
** Measured according to JASO M347-95 (sonic).
The shear stability is better as SSI lowers
Mechanism of Viscosity Index Improver (VII)
Figure 1 shows a schematic diagram of the dissolution state of VII and the viscosity behavior of lubricating oil.
When VII is not added [A, C in Figure 1], the viscosity changes significantly with temperature, so the viscosity of low-viscosity base oils falls outside the proper range at high temperatures and that of high-viscosity base oils at low temperatures. By adding VII to low-viscosity base oils, viscosity can be maintained in the proper range over a wide temperature range from low to high temperatures [ B in Figure 1].
This is because the solubility of VII in lubricating oil changes depending on temperature, and at high temperatures, the molecular chains of VII are extended and broadened, which significantly increases the viscosity of the lubricating oil, while at low temperatures, the molecular chains of VII are contracted and become small and rounded, which has a smaller effect on increasing the viscosity of the lubricating oil.
ACLUBE POUR POINT DEPRESSANT
Lubricating oils obtained by adding ACLUBE products to base oils have excellent fluidity even at temperatures below freezing point (Table 4).
