SMD-13 / SMD-33S / SMD-53N


Usage

     Decrease mooney viscosity and prevent the tendency of re-agglomerating silica in rubber

 

Characteristic

     Improve the property of the rubber and reduce the usage of silan-coupling agent and energy in mixing process.
     Save the cost of manufacturing

  • * SMD-13
    · Mixture of fatty acid and Zinc/Potassium soap. Improve the flow and prevent the re-agglomerating of filler.
      Applicable on any kind of compounds
  • * SMD-33S
    · Mixture of fatty acid and fatty acid soap. Improve the rate of extrusion and sticking of mixing roll
  • * SMD-53N
    · Mixture of fatty acid-amid, not include metal(;Zinc, Potassium and Sodium etc.)
    · Specialized to high silica compound. Decrease the mooney viscosity and can keep the mixed compound for a long time
