Specifications
refrigerator polyurethane foam-cp/ip foaming agent
-good flowability
-low thermal conductivity
Products Introduction
Refrigerator polyurethane foam DJD-103 blend polyols use CP or CP/IP 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 4-8 minutes.
