Characteristics

  • Mainly used as an accelerator for natural and synthetic rubber.
  • Functions as a plasticizer and peptizer in the chloroprene rubber.
  • Provides a foam stabilizing effect in the foaming process of latex.
  • Used as an activator for thiazole,thiuram,and sulfenamide accelerators; when used in combination with accelerators MBTS and TMTD,it is suitable for continuous vulcanization. It offers good flex resistance and excellent storage stability.
  • May cause discoloration and is not suitable for white or light-colored products, nor for rubber products that come into contact with food.
  • Usage level: 1-2 phr as a secondary acceletor;0.1-0.5 phr as a secondary accelerator for thiazoles.
