PU Foam is a rigid cellular polyurethane of low specific gravvity with predominatly closed cell structure. Cellular polyurethanes are specific type of polymers produced from compounds containing active hydrogen atoms. These may be either polyesters or polyether based polyols.
USES
Polyurethane foams have unique properties like high strength to weight ratio, low thermal conductivity, low water vapour transmission, buoyancy and ideal electrical properties.
