Abstract: 
District heating pre-insulated pipes are a sandwich structure of material layers. Polyurethane foam bonds the medium pipe with the casing, providing an insulating function as well as a load bearing function. The high toxicity of the di-isocyanates required for its manufacturing triggers the need for a replacement. In this work, alternatives have been researched and developed considering the requir...

Vorgedämmte Fernwärmerohre bestehen aus mehreren Schichten unterschiedlicher Materialien. Im Standardfall verbindet ein Polyurethanschaum das Mediumrohr aus Stahl mit der Ummantelung aus Polyethylen. Der Schaum hat die Funktion der Wärmedämmung und ist für den kraftschlüssigen Verbund zwischen den Schichten zuständig. Durch die hohe Toxizität der für die Herstellung von Polyurethan erforderlichen ...
