Application

Characteristics

  • Used as an antioxidant for natural rubber(NR), synthetic rubber (SR), and their latices, providing effective protection against copper-induced degradation.
  • Functions as a secondary antioxidant and thermal stabilizer for diene plastics.
  • Serves as an auxiliary heat sensitizer and gelling agent in latex foam compounds,helping to reduce instability during processing.
  • When combined with amine or phenolic antioxidants, demonstrates synergistic effects by decomposing hydroperoxides generated during aging, significantly improving resistance to thermal and oxidative degradation. Particularly effectivein peroxide curing systems.
  • When used together with accelerators M and DM, provides enhanced resistance to aging caused by harmful metal ions.
  • Easily dispersed in rubber; non-discoloring under sunlight.Suitable for transparent, light-colored,and bright-colored rubber products.
  • Not suitable for rubber products intended for food contact.
