Abstract: The invention concerns a foam consisting of at least 70 wt. % of carbon, having an average cell size more than 30 mu m, porosity between 35 % and 99.7 %, a percentage of open cells higher than 90 %, and comprising linking elements between the cells, which, viewed in cross-section, form a triangle with inward-curving sides. Inside the surface of the cross-section, the sum of the surfaces having a cavity constitutes less than 5 % of the total cross-sectional area of the linking elements. The invention also concerns the use of said foams consisting for the major part of carbon in electrical and electrochemical applications, in the form of filtering material, heat insulation material, support material, storage material and as starting material for other transformations. The invention further concerns a method for producing a foam consisting of at least 70 wt. % of carbon, by pyrolizing synthetic foams. Said method is characterized in that the synthetic foams used contain at least 30 wt. % of a polymer material having a nitrogen content higher than 6 wt. %, and having a porosity between 20 and 99 %, as well as a percentage of open cells higher than 1 %.

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).
