    Abstract: The present invention relates to a process for producing polyurethane-coated conduit elements, in which (a) aliphatic polyisocyanate is mixed with (b) compounds having at least two hydrogen atoms which are reactive toward isocyanate, (c) catalyst and (d) optionally other auxiliaries and/or additives, to form a first reaction mixture, the reaction mixture is applied directly or indirectly to a pipe and allowed to react to form a polyurethane layer, wherein the compounds having at least two hydrogen atoms which are reactive toward isocyanate comprise a compound based on an alkoxylation product of an aromatic starter molecule. The present invention further relates to conduit elements which can be obtained by such a process.

    Abstract: A process for producing a polyurethane-coated conduit element includes mixing a) a mixture of aromatic and aliphatic polyisocyanate with, b) at least one polymeric compound having at least two hydrogen atoms which are reactive toward isocyanate, c) at least one chain extender, d) a catalyst, and e) optionally at least one other auxiliary, additive, or both, to form a reaction mixture; applying the reaction mixture to a conduit element; and allowing the reaction mixture to react to form a polyurethane layer. The polyurethane-coating conduit element is suitable for maritime applications in the oil and gas industry, which polyurethane has improved hydrolysis stability at high temperatures and nevertheless satisfies the high mechanical demands in the oil and gas industry.

    Abstract: Described herein is a process for preparing a polyurethane elastomer including the steps of (A) preparing an isocyanate prepolymer (a), where the isocyanate prepolymer has an isocyanate content in the range of ≥1 wt.-% to ≤9 wt.-%, and (B) preparing a reaction mixture by mixing at least one epoxy compound (b) with the isocyanate prepolymer (a) in presence of at least one catalyst (c), and where the amount of the alkali metal or alkaline earth metal salt is 0.00001 to 0.1 mol per kg of the total weight of the isocyanate prepolymer (a), the epoxy compound (b) and the catalyst (c), and heating the mixture to at least 80° C. to obtain the polyurethane elastomer. Also described herein are a polyurethane elastomer obtained by the process and a method of using the polyurethane elastomer as part of a roller or as a sealant.
