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. demold time is 6-8 minutes.
