Advantages
  • Lower raw material costs.
  • Lower power consumption and other processing costs resulting from shorter mixing cycles.
  • Low calendering, mixing and extrusion temperature.
  • Reduction of die-swell.
  • Better air venting properties between bladder and inner liner during vulcanisation.
  • Reduced air permeability in an inner liner (results in reduction of inner liner thickness).
  • Improved flex fatigue resistance.
