Common insulation materials, rock wool, polystyrene foam board (EPS), extruded polystyrene foam insulation board (XPS) and polyurethane (PUR). From three aspects: thermal insulation, flame retardant, economic analysis, the comprehensive performance of polyurethane rigid foam is the standard of insulation material, can be widely used in building energy saving.
High environmental protection: the use of a cubic meter of polyurethane insulation material, a year can reduce carbon dioxide emissions 270 kg. According to 1 years of consumption of 1000000 tons of polyurethane insulation materials, a year can reduce carbon dioxide emissions 7000000 tons.
Flame retardant: only the polyurethane material in the heat preservation material has the flame retardant type.
Heat insulation: the thermal conductivity coefficient of the hard foam polyurethane insulation material is 0.017-0.024, and the heat transfer coefficient is the lowest, and the heat preservation performance is the best.
Polyurethane hard foam insulation material is an ideal material for building energy conservation, low carbon environmental protection, has the quality of light, high strength, heat insulation, sound insulation, shock resistance, and so on, which is widely used in industrial manufacturing, construction, packaging, transportation and other industries.
