Product Description

Rigid Polyurethane one shot process Isocyanate and Polyol for Rice Steamer Cabinet

DFR1314B is rigid polyurethane system, uses the HCFC-141B as blowing agent, which is the substitution of CFC-11 in polyurethane industry, it applies to refrigerators, icebox, Rice Steamer Cabinet 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 quick
