About Viscosity Improver Polimers Shamaprene - 141

SHAMAPRENE 141 is a high-performance Olefin Copolymer (OCP) based Viscosity Index Improver specially developed for automotive and industrial lubricant formulations. It is designed to improve the viscosity-temperature relationship of lubricating oils, helping oils maintain stable viscosity under both low and high temperature operating conditions.

The product is manufactured using highly stable polymer technology with narrow molecular weight distribution, ensuring excellent thickening efficiency, shear stability, oxidation resistance, and long lubricant service life. SHAMAPRENE 141 is widely used in multigrade engine oils, hydraulic oils, gear oils, transmission fluids, and industrial lubricants.
