Rigid PU Foam :Blend Polyol SDJ2401/SDJ2402
DESCRIPTION
SDJ2401/SDJ2402 is mainly used for thermal insulation layer of the refrigerator and freezer. SD2401 is designed for cyclopentane material as the physical blowing agent, while SD2402 is designed for 141b as the physical blowing agent. It used together with isocyanate(PM-200) to make rigid PU foam through PU injection foam machine. The foam produced has the characteristics as following:
1.Good flowing property
2. The pore in the core of the foam is very less.
3. Low thermal conductivity and so on.
