Irganox® 1010 is a highly effective, non-discoloring, sterically hindered primary phenolic antioxidant stabilizer that protects organic substrates against thermo-oxidative degradation.
Product Description
Irganox 1010 is a highly effective, non-discoloring, sterically hindered primary phenolic antioxidant stabilizer that protects organic substrates against thermo-oxidative degradation. It offers good compatibility, high resistance to extraction, low volatility, and is odorless; it is manufactured using a tin-free process and can be used in combination with other additives such as co-stabilizers (thioethers, phosphites, phosphonites), light stabilizers, and other functional stabilizers. See also Irgafos 168, a phosphite secondary antioxidant that the manufacturer specifically recommends blending with hindered phenols of the Irganox range for particularly effective, long-term thermooxidative protection.
