This company, a division of Emerald Performance Materials, has added GOOD-RITE® 3131 to its portfolio of antioxidants for lubricants. The low-DPA-containing liquid antioxidant reportedly decreases extractables and volatility, thereby improving the antioxidant efficiency, scorch, and long-term stability, and reducing discoloration in applications.

Based on an octyl butylated diphenylamine chemistry, GOOD-RITE 3131 is formulated to prevent discoloration/scorch by providing thermo-oxidative stabilization of polyols, elastomers and adhesives. The liquid can reportedly offer high activity at low use levels (less than 0.5%), allowing it to be used in automotive, aviation and industrial applications specifically related to the use of flexible polyurethane foams, hot-melt adhesives, and high-performance gear oils.
