Polyurethane Chemical Package Combined Materials Isocyanate And Polyol Foam Raw Material
Description of Closed Cell Two Component Polyurethane
1) fine and uniformity cells
2) low thermal conductivity
3) perfect flame resistance
4) good low temperature dimentional stability.
It applies to all kinds of thermal insulation engineering which uses the spray technology, such as cold rooms, pots, large-scale pipelines and construction metope etc.
