Product Introduction
DJD-102 blend polyols use HCFC-141B as blowing agent, as the transition substitutes in polyurethane industry, which applies to refrigerators, freezers and other thermal insulation products. The characteristics are as follows:
1.excellent flowability, the density of the foam is well-distributed, and the thermal conductivity is low;
2.excellent low-temperature dimensional stability and good cohesiveness;
3.demold time is 6-8 minutes.
