INTRODUCTION
DonCool 106 blend polyols use CP mixed with HFO-1233zd as blowing agent, it applies to refrigerators, freezers, electric water heaters and other products thermal insulation, the characteristics are as follows,
1-Excellent flowability, foam density distributes uniformity, low thermal conductivity
2- Outstanding low temperature dimension stability and cohesiveness
3-Demoulding time is 4-8min.
