    Abstract: PROBLEM TO BE SOLVED: To provide a light stable polyurethane foam which can be produced by using a common use starting material in the polyurethane chemistry, excellent in mechanical properties, especially in elongation and high tensile strength. SOLUTION: The polyurethane foam is produced by reacting a polyisocyanate a) and the compound b) having at least two hydrogen atoms which reacts with an isocyanato group, and a polyisocyanate a) is composed of an aliphatic di- or polyisocyanate, and the compound b) having at least two hydrogen atoms which reacts with an isocyanate group is produced by the method having at least one kind of acrylate polyol.

    Abstract: PROBLEM TO BE SOLVED: To provide a two-component polyurethane contg. a reactive diluent which is easy to manufacture and incorporated into a polyurethane without difficulty, and has no side-reaction with the structural component of the polyurethane. SOLUTION: This polyurethane comprises at least two-functional polyisocyanate component and polyol component, and the polyol component contains at least a cyclic acetal contg. a hydroxyl and/or a ketal. This method of manufacturing the polyurethane comprises a reaction of at least two- functional polyisocyanate with a compd. contg. an active hydrogen, and the compd. contg. an active hydrogen contains the cyclic acetal and/or the ketal as a reactive diluent.

    Abstract: The invention relates to a thermoformed soft foam, made from polyurethane, obtained by reaction of polyisocyanates with polymeric polyols to give a polyurethane soft foam with subsequent irreversible thermoforming of the soft foam obtained thus, at temperatures above the glass temperature of the thermoplastic polymers and the use of polymeric polyols to produce a polyurethane soft foam which may be irreversibly formed in moulds at temperatures of 120 DEG C to 250 DEG C.

    Abstract: Reticulated flexible polyurethane foams are prepared by reacting organic and/or modified organic polyisocyanates (a) with a polyetherol mixture (b) and, if required, further compounds (c) having hydrogen atoms reactive toward isocyanates, in the presence of water and/or other blowing agents (d), catalysts (e) and further assistants and additives (f), by a process in which the polyetherol mixture (b) comprisesb1) at least one difunctional or polyfunctional polyetherol having an OH number of from 20 to 150 mg KOH/g, based on propylene oxide and/or butylene oxide and ethylene oxide and having an ethylene oxide content of more than 40% by weight, based on the total amount of alkylene oxide used, (b1.1) and, if required, further difunctional or polyfunctional polyetherols having an OH number of from 20 to 150 mg KOH/g, based on propylene oxide and/or butylene oxide and ethylene oxide and having an ethylene oxide content of not more than 40% by weight, based on the total amount of alkylene oxide used, which have a content of primary OH groups of more than 40%, (b1.2), with total amounts of the component (b1) of at least 70% by weight, based on the total weight of the component (b), (b1.1) being present in amounts of at least 50% by weight, based on the total weight of the component (b), andb2) at least one difunctional or polyfunctional polyetherol based on propylene oxide and/or butylene oxide and having an OH number of more than 25 mg KOH/g, in amounts of not more than 30% by weight, based on the total weight of the component (b),and silicone stabilizers are used in amounts of from 0.02 to 5% by weight, based on the total weight of the components (b) to f). The reticulated flexible polyurethane foams themselves prepared in this manner are used for upholstery purposes, for cavity filling and as support medium and filter medium.
