Abstract:
A polyurethane composite element has one or more gaps containing a polyurethane foam. The polyurethane foam has a density of 16-40 kg/m3 and a closed cell proportion of 50-90% determined according to ASTM D6226-2010 Standard Test Method. The polyurethane foam is formed by applying a polyurethane composition into the gaps in situ. A process for producing a polyurethane composite element is also described.
