front page District heating District cold Special tubes Quality Company Contact information News Polyurethane insulation Our district heating elements use hard polyurethane foam as insulation, which is foamed between a steel pipe and a plastic pipe. The quality of the insulation complies with the LT mark and Euroheat & Power recommendations. Polyurethane insulation is the result of a reaction between two substances, an isocyanate and a polyol. The propellant is cyclopentane. Properties of polyurethane foam LT mark requirements nominal average density 80 kg / m 3 minimum density 60 kg / m 3 number of closed cells 88% compression range, radial direction 300 kPa 150 kPa when aged adhesion to the steel tube in the axial direction 120 kPa 60 kPa when aged thermal conductivity, flow tube It = 120 O C 0.031 W / K m 0.034 W / K m when aged Print this page Publishing system SEO SiteSystem
