A process of making higher density flexible polyurethane foam from waste polyurethane foam is accomplished by powdering the waste polyurethane foam and mixing it with any foamable polyurethane composition and moulding the mixture in a mould. Before mixing the powdered foam is sufficiently dried and screened to get a uniform particle size.

Foamed isocyanate-based plastics products are made by reacting an organic polyisocyanate with an isocyanate-reactive material, especially a polyol, the polyisocyanate and optionally the isocyanate-reactive material having carbon dioxide dissolved therein under pressure.

Cold-cured molded polyurethane flexible foams having improved vibration damping properities are made by foaming in the presence of (1) a high molecular weight predominantly linear siloxane polyoxyalkylene block copolymer and (2) a solvent which is compatible with the block copolymer and which has a viscosity of 3 to 100 cps and a surface tension between 15 to 60 dynes/cm.

A composition comprising a combustible material, especially a polyurethane, and a smoke and toxic gas (STG) suppressant system, comprising (A) an STG-suppressant with (B) a combustion rate- and/or flame temperature-reducing component, or (C) a char-stabilizer, components (B) and (C) preferably both being present.

1. Spacer foil for mould and pattern construction, characterised in that it is produced by hardening 100 parts by weight of a mixture of 45-60 parts by weight of an internally plasticized epoxy resin of low epoxide value, 5-10 parts by weight of an external plasticizer and 35-45 parts by weight of spherical-amorphous filling material with 9-13 parts by weight of a polyamine hardener.

A method for repairing perfluorocarbon copolymer cation exchange membranes involves partially solvating a quantity of a perfluorocarbon copolymer having a desired pendant cation-exchange functional group, using a solvating dispersion medium. The composition is applied to areas of the membrane to be repaired and the dispersion medium is then removed.
