    Abstract: In a composite element comprising layers of (i) polyisocyanate poly-addition product (PU), (ii) optionally at least one plastic, (iii) a gas permeation barrier and (iv) at least one thermoplastic, layers (iii) and (iv) are bonded together by melting a layer (iiia) between them. Independent claims are also included for: (a) sandwich elements with the following layers: (iv) 1-25 mm thermoplastic, (iii) 0.1-200 micro m metal foil coated on the opposite side from (i) and (ii) with 20-500 micro m thermoplastic (iiia) which is melted to bond (iii) with (iv), (ii) optionally 5-1000 micro m plastic, (i) 0.5-80 cm PU and then layers (ii), (iii) and (iv) as above; (b) tubes with the following layers: (iv) as above and/or metal as inner tube, (i), (ii), (iii) as above and (iv) (above) as an outer tube; (c) tubes with the following layers: (iv) plastic as above and/or metal as inner tube, (iii), (ii), (i), (ii), (iii) as above and (iv) plastic (above) as an outer tube; (d) the production of composite elements by reacting isocyanates with NCO-reactive compounds in the presence of blowing agents and optionally catalysts and other additives etc. in a reaction space bounded by layers (ii) (optional), (iii) gas barrier material, (iiia) 20-500 micro m thermoplastic and (iv) 1-25 mm thermoplastic(s), so that layer (iiia) is melted by the heat of reaction and binds layers (iii) and (iv) together after cooling; and (e) composite elements obtained by (d).
