Emerald Polymer Additives expands antioxidant technology

January 24, 2012

Emerald Polymer Additives, a division of Emerald Performance Materials, introduced Good-Rite 3131 to its portfolio of antioxidants for lubricants. The low-DPA-containing liquid antioxidant decreases extractables and volatility, thereby improving the antioxidant efficiency, scorch and long-term stability, and reducing discoloration in applications said the company. Based on an octyl butylated diphenylamine chemistry, Good-Rite3131 is formulated to prevent discoloration and scorch by providing thermo-oxidative stabilization of polyols, elastomers and adhesives. As an easy-to-use liquid with low volatility, it offers high activity at low use-levels (less than 0.5 percent). Such attributes make it ideal for use in automotive, aviation and industrial applications specifically related to the use of flexible polyurethane foams, hot melt adhesives and high-performance gear oils.
