US Patent:

20060035990, Feb 16, 2006

Filed:

Aug 11, 2005

Appl. No.:

11/201886

Inventors:

Roger Hennington - Houston TX, US
Donald Ridgway - Spring TX, US
Robert Grigsby - Spring TX, US
Robert Sawitski - Romulus MI, US
Jennifer Pratt - Round Rock TX, US

Assignee:

Huntsman Petrochemical Corporation - The Woodlands TX

International Classification:

C08J 9/00

US Classification:

521099000

Abstract:

The present invention provides processes for producing re-bonded polyurethane foam constructs that are useful in applications such as carpet underlayments. According to the invention, a tertiary amine is employed as a catalyst either alone, or preferably in combination with other catalysts in a binder which comprises an organic isocyanate and a polyol. Inclusion of a tertiary amine as a catalyst dramatically increases production throughput.

US Classification:

521065000, 502167000, 521189000

Abstract:

Provided herein are catalysts useful in providing foam products which are produced using an organic poly isocyanate as a starting material. A catalyst according to the present invention includes the tris-(hydroxyethyl)methyl ammonium cation, and optionally potassium cation, in combination with a variety of possible counter anions present to maintain charge balance and for compatibility. A catalyst according to the invention is preferably used in conjunction with one or more conventional tertiary amine catalysts in a foam producing process. The foams may be polyurethane foams, polyisocyanurate foams, flexible foams, or elastomeric foams.
