  • OUR JOURNEY TO BECOMING THE GLOBAL PERFORMANCE ADDITIVES POWERHOUSE

    We innovate and drive change to create value with a passion for safety, chemistry, and extraordinary results.

  • MEET MODERN LUBRICANT DEMANDS

    SI Group’s newest portfolio addition, ETHANOX? 1315 lubricant antioxidant, offers lower overall volatility under higher temperature conditions which extends the effective usage range of the lubricant application. Furthermore, it provides excellent performance in standalone applications while remaining soluble in today’s base stocks.
