Abstract: The invention relates to a sandwich component composed of at least two building material plates which are arranged essentially parallel to one another at a distance from one another and have a polyurethane foam core between the spaced building material plates, wherein the ratio of the greatest measured compressive modulus of the polyurethane foam core in a direction oriented parallel to the building material plates to the compressive modulus of the polyurethane foam core in a direction oriented perpendicular to the building material plates is less than 1.7. To produce the sandwich components, a mixture of (a) at least one polyisocyanate component, (b) at least one component which comprises at least one polyfunctional compound which is reactive toward isocyanates and (c) at least one blowing agent is introduced by the high-pressure injection method into a hollow space between spaced building material plates. The process makes it possible to produce sandwich components whose foam core has reduced anisotropy combined with good insulation values.

Abstract: The invention relates to flame retardant compositions comprising heptaphosphorus-derived compounds and to novel heptaphosphorus-derived compounds.These heptaphosphorus-derived compounds are especially useful for the manufacture of flame retardant compositions based on thermoplastic polymers, especially polyolefin homo- and copolymers, polycondensates, such as polyamides, or polyesters and duro-plastic polymers, such as the ones based on polyepoxides.
