An isocyanate reactive composition including at least one component selected from the group consisting of a polyether polyol, a polyester polyol, a polyether polyamide and a polyester polyamide; one or more amine components, each of said amine components having a given structure. In some embodiments, the average number of nitrogen atoms of said amine components is in the range of 5 to 10.

Composition

An isocyanate reactive composition comprising In some embodiments, the average number of nitrogen atoms of said amine components is in the range of 5 to 10.

An isocyanate reactive composition comprising

Composition to reduce the amount of aldehydes emitted from polyurethane foams

The present disclosure provides a method for reducing the aldehyde content in an amine catalyst by treating the amine catalyst with a treating agent selected from a cyclic urea substituted with at least one isocyanate reactive group, a free radical scavenger and a mixture thereof. The treated amine catalyst may then be used in the production of polyurethane materials which exhibit reduced aldehyde emissions.

Reduction of aldehydes in amine catalysts

The present disclosure relates to pyrrolidine-based catalysts for use in a polyurethane formulation. The polyurethane formulation includes the pyrrolidine-based catalyst, a compound containing an isocyanate functional group, an active hydrogen-containing compound. The use of such catalysts produces high quality polyurethane foam while reducing environmental concerns that can arise during the production of polyurethane foam as well as in the foam that is produced.

Pyrrolidine-based catalysts for use in polyurethane materials

The present disclosure provides a method for reducing the aldehyde content in an amine catalyst by treating the amine catalyst with an organic acid. The organic acid-treated amine catalyst may then be used in the production of polyurethane materials which exhibit reduced aldehyde emissions.

An amine according to the invention has a formula(CH)NCHCHOCHCHCHN(R1)(R2)wherein R1 is selected from (CH)NCHCHOCHCHCH&#x2014; and R2 is selected from the group consisting of H&#x2014;, CH(CH)&#x2014;, HO(CH)&#x2014; and (CH)NCHCHOCHCHCH&#x2014;, n being an integer in the range of 0 to 5, m being an integer in the range of 2 to 4.
