Properties include

  • Controlled cell size foam
  • Closed or open cell foam
  • Excellent strength to density relationship
  • Self-extinguishing and exhibits fire retardant properties
  • Excellent as thermal insulation
  • Capable of meeting international building regulation requirements
  • Non-flammable, but will support combustion by direct contact with open flame or exposure to temperature in the range of 315°C (600°F)
  • Can be carbonized
  • For thermal conductivity, the closer the cells to each other, the less transfer of heat from one to another
