Polyurethane thermal insulation material production energy consumption is low, the use of energy saving effect is significant, but also has the characteristics of earth saving, land saving, environmental protection, waste, heat insulation, heat preservation, fire prevention, light weight, reduce transportation costs, convenient construction, low cost and so on. Has become the fifth largest plastic after polyethylene, polyvinyl chloride, polypropylene, polystyrene, the global total output has exceeded 10 million tons/year. As a kind of polymer material with excellent performance, polyurethane insulation material is the best insulation material in the world. Has become the fifth largest plastic after polyethylene, polyvinyl chloride, polypropylene, polystyrene.
Rigid polyurethane insulation material has light weight, low thermal conductivity, good heat resistance, aging resistance, easy to bond with other substrates, combustion does not produce droplets and other excellent properties, in refrigerators, containers, leather, shoe and textile fields have been widely used; The popularization in the field of building energy saving will create a great development space for our polyurethane industry.
