VI-R02 High Density PU Blend Polyols for Spray Foam
VI-R02 Blend Polyols belongs to the spray blend polyols series with a pale yellow to brown
yellow transparent liquid .After reacting with isocyanate at the certain ratio to produce foam.
Mainly used in the building roof insulation project, cold storage, large-scale pipelines project
and all types of abnormity thermal insulation projects. It have the advantage of smooth and
uniformity cell,low thermal conductivity; good flame resistance and excellent low temperature
dimentional stability and so on.
