Application

Characteristics

  • Used as an antioxidant in natural rubber,synthetic rubber,and their latices, providing effective protection against copper degradation; also employed as an auxiliary antioxidant and heat stabilizer for diene-based plastics;can be used as an acid copper plating brightener in the electroplating industry.
  • Exhibits a synergistic effect when used in combination with other antioxidants (e.g., amines, phenolics),decomposing hydroperoxides generated during rubber aging and imparting excellent heat and oxygen aging resistance, with enhanced effectiveness in peroxide curing systems.
  • Disperses readily in rubber and shows minimal discoloration under sunlight,making it suitable for light-colored and bright-colored products. However, due to its bitter taste, it is not recommended for rubber articles intended for food contact.
  • Usage level: 1.0-1.5 phr; in latex foam rubber, due to its destabilizing effect on latex, the dosage should be reduced to 0.5 phr.
