Products Introduction
Rigid Polyurethane Blend Polyols Foam System for Refrigerators Insulation
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 6-8 minutes.
