INTRODUCTION
DonCool 102 is blend polyols, uses the HCFC-141B as blowing agent, which is the substitution of CFC-11 in polyurethane industry, it applies to refrigerators, icebox and other thermal insulation products, the characteristics are as follows,
1. Excellent flow ability, foam density distributes uniformity, low thermal conductivity
2. Excellent low temperature dimension stability and cohesiveness
3. Demould time 6~8 minutes
