Rigid Polyurethane Blend Polyols for Coolers DJD-101S

DJD-101S blend polyols use water as blowing agent which applies to coolers,barrel insulation and other insulation products. The characteristics of the products are as follows

  • 1.excellent flowabilitythe density of the foam is well-distributed and the thermal conductivity is low
    2.excellent low-temperature dimensional stability and good cohesiveness;
