Special structures 2
The cells are separated from each other in closed cell foam plastics (e.g.: pipes, joints and gaskets). The closed cells prevent air exchange and don’t exert capillary attraction on liquids. The closed cell structure of PU spot foam ensures a continuous surface that meets this demand outstandingly. If there is no vapor pressure, the insulation won’t have any moisture content.
Because of its closed cell structure, ECOPUR-HS PU foam can be used wherever insulation is needed. By these features, it is waterproof and rotproof across the whole cross section, and this way, it can be used as a water sealing, too.
A closed insulation layer comes into being by insulation of a cooling pipe with polyurethane spray-foam, there is no dripping water formation.
