INTRODUCTION
Doncool 103 is blend polyols uses 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 flow ability, the density of the foam is well-distributed, and the thermal conductivity is low
2. Excellent low-temperature dimensional stability and good cohesiveness;
3. Demoulding time is 6-8 minutes.
