Rigid Polyurethane Blend Polyols for Refrigerators
DJD-103
Products Introduction
DJD-103 blend polyols use CP or CP/IP as blowing agent which applies to refrigerators freezers 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;
3. demould time is 6-8 minutes.
