Promix  melt coolers / P1 cooling mixers enable a lower foam density in the production of XPS insulation boards

Your advantages

  • More uniform and finer foam structure
  • Higher mechanical strength thanks to low proportion of open cells
  • Increased line throughput, especially with thick sheets
  • Lower foam density
  • Savings in blowing agent and flame retardant
