Technical Data Sheet

T612 Ethylene-propylene Copolymer

Description:

T612 Viscosity index improver is primarily used in blending multi-grade gasoline engine oils. T612 can boost the viscosity efficiently and boost the viscosity index of the lubricating oils. This product also has good compatibility with pour point additives.

Key Performance Benefits

1.Strong thickening capacity                         

2.Excellent thermal and chemical stability                                    

3.Greatly improving the viscosity index         

4.Good compatibility with pour point depressant 

5.Good shear stability and adhesion promotion ability
