Ethylene-propylene copolymer

Solid amorphous olefin copolymer, analog LS-T770、LS-T771, designed to increase the viscosity index of motor oils of high and middle class. It is characterized by good shear stability and increased low-temperature properties. Higher ethylene content.

It is used as a thickening additive for the production of motor oils and fluids for automatic transmissions. It has good susceptibility to depressant additives.

Conducted in motor oils for gasoline engines according to the methods of Sequence IVA, Sequence VG and Sequence VIII at SWRI (Southwest Research Institute in Texas)
