Viscosity Improver Polimers Shamaprene - 161

About Viscosity Improver Polimers Shamaprene - 161

Shamaprene 161 is a premium-grade Viscosity Index Improver (VII) polymer developed for lubricant and engine oil formulations. It is based on highly stable Olefin Copolymer (OCP) technology designed to improve viscosity stability over a wide temperature range. The product provides excellent thickening efficiency, thermal stability, and shear resistance, making it suitable for high-performance automotive and industrial lubricants.

Shamaprene 161 helps lubricating oils maintain consistent viscosity at both high and low operating temperatures. It reduces excessive thinning at elevated temperatures and minimizes oil thickening during cold starts, resulting in better lubrication performance and longer equipment life.
