Product Introduction

Polyurethane polyther polyol foam system for refrigerator and freezer insulation

DJD-102 blend polyols use the HCFC-141B as blowing agent, which is the substitute product 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- Outstanding low temperature dimension stability and cohesiveness

3-Demould time 4~8 minutes
