Spray Polyurethane foam is a chemical product created by two materials, isocyanate and polyol and the mixing ratio is about 1/1, which react when mixed with each other and expand up to 30-60 times its liquid volume after it is sprayed in place. This expansion makes it useful as a specialty insulation layers (on flat or waved roofing or tank surfaces) and packing material which forms to the shape of the product being packaged. K-factor is the term given to thermal conductivity. The lower the K-factor of an insulation product, the more effective the insulation properties. Spray polyurethane foam comes in a range of densities and cell structure. Our spray polyurethane foam has the lowest K-factor of readily available spray foam insulation used in homes and buildings. On the other hand, at below 15°C, foaming efficiency becomes low and adhesive strength becomes poor. Our technical team success to solve this matter. The available range of density for production of thermal insulation foam is 20-50 (kg/m3).
