Polyurethane foams co-blown with a mixture of a hydrocarbon and a halogenated olefin
This invention relates to rigid polyurethane foams which are co-blown with a mixture of a hydrocarbon blowing agent and a halogenated olefin blowing agent. This invention also relates to a process for preparing these rigid polyurethane foams, and to an isocyanate-reactive component containing a polyol blend and the mixture of blowing agents. Phase stable isocyanate-reactive blends are also described.
TWO-COMPONENT POLYURETHANE COMPOSITION FOR THE PRODUCTION OF LARGE SCALE MODELS AND TOOLS BY 3D PRINTING
A two-component polyurethane compositions including (i) a polyol component A comprising a tri- or higher functional polyol P1 having an OH equivalent weight of from 60 g/mol to 250 g/mol and a di- or tri-functional polyether or polyester polyol P2 which is different from the polyol P1; and (ii) an isocyanate component B comprising at least one polyisocyanate I. Polyurethane compositions have surprisingly been found to be suitable for 3D printing processing, where they provide printed 3D objects with reduced tackiness even shortly after the printing. In addition, the invention provides processes for the production of three dimension objects form such compositions as well as three dimensional objects prepared accordingly and the use of corresponding compositions in 3D printing processes.
RETORT ADHESION COMPOSITION

Methods for Reducing Aldehyde Emissions in Polyether Polyols and Polyurethane Foams
Polyurethane foams are made by curing a reaction mixture that contains an aromatic polyisocyanate, at least one isocyanate-reactive material having an average functionality of at least 2 and an equivalent weight of at least 200 per isocyanate-reactive group, at least one blowing agent, at least one surfactant and at least one catalyst, and a certain 3-oxopropanamide compound. Foams so produced emit low levels of aldehydes.
