Specifications:

  • 445 is heat resistant (slightly staining) antioxidant. It is a slightly staining & discoloring antioxidant being stable at high temperature, is used for protection against heat and oxidative degradations in NR and synthetic rubbers including BR, SBR, NBR, CR and EPDM covering uses in beltings, hoses, seals, gaskets and other automotive/industrial rubber products. In combination with synergistic antioxidants it provides an extremely effective antioxidant system for EPDM and NBR compounds for high temperature applications. Often used as aqueous dispersions in latex compounds (SBR, Carboxylated SBR and NR) for improving resistance to heat and embrittlement during aging with as little 0.5 phr in the compound. Typical dosages in rubber vary from 1 to 3 phr depending on the application envisaged.

Storage and Handling:

  • Store in a cool, dry & well-ventilated place, local exhaust recommended. Keep container closed when not in use.
  • No special handling precautions are necessary. Normal precautions to avoid contact with skin and eyes should be followed. For eyes, flush with plenty of water and seek medical advice.
