Polyurethane insulation is a kind of insulation product widely used at low pressure, mainly suitable for hot and cold application.
The polyurethane thermal insulation have the following characteristics:
A. Low density and low thermal conductivity. Under normal conditions, the density of rigid polyurethane foam is 35-40 kg/m3. But compared with other thermal insulation materials, rigid polyurethane foam has very good thermal insulation properties, that is to say, if it reaches the same thermal insulation performance, rigid polyurethane foam is thinner than other materials. At the same time, the application of rigid polyurethane foam saves space.
B. Wide application temperature can be used normally between -40-90íŠ, with high dimensional stability, good weather resistance and chemical stability.
C. The high-strength polyurethane rigid foam insulation has high compressive strength, cohesiveness and shear strength, and can adapt to the normal deformation of the base material in contact with it without cracks, hollowing, etc.
D. Low moisture absorption, air-tight polyurethane rigid foam insulation also has low moisture absorption. This means that it has a longer life span than other thermal insulation materials, which can more effectively play its excellent thermal insulation performance.
E. Good fire resistance. By adjusting the formula, the rigid foam polyurethane material can meet the requirements of various international standards. It will not melt and drip like EPS or XPS materials, and during the incineration of rigid foam polyurethane materials, a coking maintenance layer will be formed to restrain the spread of incineration. In addition, the metal veneer can further enhance its flame retardant performance.
F. Non-toxic, non-irritating and non-biological parasitic polyurethane rigid foam is non-toxic, non-irritating, safe and convenient to operate. In addition, it has no biological parasitic properties, does not parasite fungi, and does not moisturize parasites.
G. Excellent building performance. Polyurethane rigid foam insulation has the characteristics of strong adhesion or composite with concrete, clay blocks, metal, wood, rubber and glass, and can be easily cut, formed and installed.
