Doncool 103 CP/IP base blend polyols

Doncool 103 CP/IP base blend polyols

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.
