Viscosity Index Improvers (VII)

Kemipex offers a broad range of Viscosity Index Improvers (VIIs), including OCP-based products (solid and liquid) for engine oils, plus PMA and styrene-based polymers in star and linear structures for enhanced viscosity-temperature control and shear stability.

With over 60 years of experience, the range covers low-SSI grades for PCMO/HDEO, high-thickening grades for brightstock replacement, and shear-stable solutions for transmissions, gear oils, and hydraulic systems including high-VI formulas for extreme conditions and low-temperature performance.

Kemipex serve both automotive and industrial lubricants, meeting API, ACEA, ILSAC, JASO, and other industry specifications, along with viscosity, HTHS, and shear stability requirements.
