Polyurethane Pipe
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.
Application and Other Characteristics
Polyurethane foams has a structural application in the construction of foam troop shelters, foam buildings for barracks, hospitals etc., which can be easily transported to remote areas.
Polyurethane foams is used in refrigeration/air conditioning in the form of Pipe Sections/Slabs.
The high buoyancy of polyurethane foam accounts for its widespread use in void filling in boats, ships, life boats and in making panels for construction of floating air strips for helicopters.
Polyurethane foams can withstand temperatures of upto 90°C. It is resistant to hot bitumen, eg.,during the laying of roof insulating slabs and such kind of behaviour prove its heat stability.
