Advantages

  • Faster Mixing Cycle ie. Less masticating with easy incorporation.
  • Improved extrusion rate.
  • Improved extrusion quality with better control on dimensions.
  • Reduction in splicing defects.
  • Reduction in electrical power consumption due to less nerve of the compound and faster mixing and extrusion.
  • Minimum increase of air permeability as compared to other grades of Reclaim Rubber.
  • No reduction in hot air aging properties.
