摘要:
The invention relates to polyurethane elastomers, a process for the preparation of these polyurethane elastomers and a the preparation of elastomeric molded parts comprising these polyurethane elastomers. These elastomers comprise the reaction product of a polyol component, chain extenders and/or crosslinking agents, one or more amine catalysts, a catalyst mixture which contains at least one organic titanium compound and at least one organic zinc compound, and optionally an organic lithium carboxylate and/or an organic bismuth carboxylate; with a polyisocyanate component.
摘要:
The invention provides solid, non-expanded, filled, molded parts which comprise an elastomeric polyurethane. This invention is also directed to a process for the production of these molded parts to the use thereof.
摘要:
The invention relates to sturdy, transparent, elastomeric polyurethane moldings, to a process for production thereof, and also the use of these moldings.
摘要:
The present invention relates to compositions containing polyether-siloxane copolymers which are based on branched SiH-functional siloxanes, where at least one of the polyether-siloxane copolymers has a radical —OR8 where R8=hydrogen or an alkyl radical having from 1 to 10 carbon atoms which is bound to a silicon atom, a process for producing polyurethane foam in which these compositions are used as foam stabilizers, polyurethane foams containing these compositions and the use of these polyurethane foams.
摘要:
Compatibilizers for mutually immiscible polyol compositions, characterized in that they comprise dispersed particles, and processes for production of these and their use in polyurethane foams.
