Cyclopentane Polyurethane Blend Polyols
DJD-103
Products Introduction
DJD-103 blend polyols use cyclopentane as blowing agent, which applies to refrigerators, freezers, and other insulation products. The characteristics of the products 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. demould time is 6-8 minutes.
