A curable composition for making polyisocyanurate comprising products obtained by combining and mixing at an isocyanate index of at least 100 at least a polyisocyanate composition, an isocyanate reactive composition comprising at least 50 mol % diols and a toughening agent comprising acrylic block copolymers.

Disclosed are a process of producing a polyurethane foam product, a polyurethane foam product pre-mix, polyurethane foam product formulation, and a polyurethane foam product. The process of producing the polyurethane foam product includes contacting a halogen containing composition with a polyurethane foam product pre-mix. The polyurethane foam product pre-mix includes the halogen containing composition. The polyurethane foam product formulation includes a polyol component, an isocyanate component, and a halogen containing compound component. The polyurethane foam product is formed by the pre-mix having the halogen containing composition.

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, at least one catalyst, and certain aldehyde-suppressing additives. Foams so produced emit low levels of formaldehyde, acetaldehyde and propionaldehyde.

Disclosed are processes, products, and compositions having tetraalkylguanidine salt of aromatic acid. The processes include providing a pre-mix comprising an aromatic carboxylic acid component and contacting a tetraalkylguanidine with the aromatic carboxylic acid component in the pre-mix to form the tetraalkylguanidine salt of aromatic carboxylic acid or producing a catalyst composition by contacting the tetraalkylguanidine with the aromatic carboxylic acid component to form the tetraalkylguanidine salt of aromatic carboxylic acid. The compositions include the tetraalkylguanidine salt of aromatic carboxylic acid. The product is formed by the tetraalkylguanidine salt of aromatic carboxylic acid.

What are described are compositions for production of polyurethane foam, comprising at least an isocyanate component, a polyol component, optionally a catalyst that catalyzes the formation of a urethane or isocyanurate bond, optionally blowing agent, wherein the composition comprises block copolymers based on OH- or amino-functionalized polyolefins and polyesters that act as foam stabilizer.

The invention relates to a method for producing soft polyurethane foam obtained by reacting a composition containing a component A1 containing at least one filled polyol, a component A2 containing compounds reactive with isocyanates and having a hydroxyl value of ≥20 to <100 mg KOH/g, the component A2 not containing any filled polyol, a component A3 containing water and/or at least one physical blowing agent, a component A4 containing auxiliary agents and additives, and a component B containing di- and/or polyisocyanates, characterized in that the reaction occurs in the presence of 0.5 to 3 parts by weight of an organic urea derivative as component C, which is obtained by reacting urea with a difunctional amine having a number-average molecular weight of 200 to 1000 g/mol. The invention also relates to a soft polyurethane foam obtainable by the method.

Disclosed herein are viscoelastic elastomeric polyurethane foams, a process for preparing them and a method of using them in making shaped articles. Further disclosed herein are of viscoelastic elastomeric polyurethane foams having improved, unique impact absorption performance.
