Rigid Polyurethane Blend polyols for Refrigerators
Product Introduction
DJD-102 blend polyols use the HCFC-141B as blowing agent, which is the substitute goods in polyurethane industry, it applies to refrigerators, icebox and other products thermal insulation, the characteristics are as follows,
1, excellent flowability, foam density distributes uniformity, low thermal conductivity
2, Excellent low temperature dimension stability and cohesiveness
3, Demould time 6~8 minutes
