PUR-situ produced by the chemical reaction of a polyol with isocyanate. The insulation directly on the object. In-situ polyurethane (PUR or PUO), a 2-component foam is a reaction of the plastic can be processed locally. It is applied in layers between 0.8 and 2 cm thickness, has a very short response time and can be applied including vertical or overhead. The special properties make the material into a high-quality insulating material.
Specifications:
Density 35 - 40 kg / m³
thermal conductivity 0.024 W / mK
closed cell content 95%
vapor diffusion resistance μ 50-100
temperature resistance +80 to -50 ° C by the liquid mixture of polyurethane foam-site is poured between the tank wall or pipe and sheet metal cover. There, the polyurethane foam in-situ on the existing cavity and then hardened in a solid insulating material.
