Abstract: Disclosed herein is a process for producing rigid polyisocyanurate foams, where (a) aromatic polyisocyanate, (b) isocyanate-reactive compounds including at least one polyetherol (b1) and/or polyesterol (b2), wherein where the number-average content of isocyanate-reactive hydrogen atoms of components (b 1) and (b2) is at least 1.7, (c) catalyst, (d) blowing agents, (e) flame retardants, (f) optionally auxiliary and additive substances and (g) optionally compounds having aliphatic hydrophobic groups and not falling under the definition of compounds (a) to (f) are mixed to afford a reaction mixture and allowed to cure to afford a rigid polyisocyanurate foam. Further disclosed herein is a rigid polyisocyanurate foam obtainable by the process.

Abstract: The present invention relates to sulfur-containing polyester polyols and to the preparation and use thereof.

Abstract: Described herein is a process for producing a polyurethane foam including mixing (a) polyisocyanate, (b) polymeric compounds having isocyanate-reactive groups, (c) silicone-free stabilizer, (d) optionally chain extending and/or crosslinking agents, (e) catalysts, (f) blowing agents, and (g) optionally auxiliaries and additives to afford a reaction mixture and reacting the reaction mixture to afford the polyurethane foam. Also described herein are a polyol component including the silicone-free stabilizer (c), a polyurethane foam obtained by the process, and a method of using the polyurethane foam in enclosed spaces or in the interior of vehicles.

Abstract: A process is useful for producing a rigid polyurethane foam, also referred to as rigid PU foam, via mixing of three streams, rigid PU foams that are obtained by that process, and the use thereof as an insulation material.

Abstract: The present invention relates to a method for producing isocyanate based lignocellulose materials in the presence of caprolactam, oligomers of caprolactam or mixtures thereof. The present invention also relates to the lignocellulose materials thus obtained and their use in furniture construction, housing construction, interior design and exhibition construction.

Abstract: The present invention relates to sulfur-containing polyester polyols and to the preparation and use thereof.

Abstract: Described herein is a process for producing composite elements comprising thermal insulation material (B), adhesive (C), and optionally at least one outer layer (A), where the thermal insulation material (B) is bonded with the adhesive (C). Also described herein are composite elements formed from thermal insulation material (B) and adhesive (C) and optionally at least one outer layer (A), producible by such a process. Also described herein is a method of using the adhesive (C) for the bonding of thermal insulation materials (B).
