Appl. No.:

10/956392

Inventors:

Bryan Kaushiva - Hurricane WV, US
William Slack - Moundsville WV, US

International Classification:

B32B 3/26
B32B 5/18

US Classification:

428304400, 521155000, 428160000

Abstract:

The present invention provides a process for producing a flexible polyurethane foam achieving reduced flammability and maintaining durability is presented. These foams are prepared by reaction of a di- or polyisocyanate/polyisocyanurate blend with polyol component optionally in the presence of a catalyst, a blowing agent, additives and a cross-linking agent. The polyisocyanurate used in the blend is a novel composition.

William E. Slack - Moundsville WV, US

International Classification:

C08G 18/00

US Classification:

528 44

Abstract:

This invention relates to novel liquid modified diisocyanate and/or polyisocyanate compositions and to a process for the preparation of these novel liquid modified diisocyanate and/or polyisocyanate compositions. These novel liquids comprise the reaction product of a diisocyanate and/or polyisocyanate component with at least one compound which corresponds to a specific structure and contains a 1,3-dicarbonyl group. These products are storage stable liquids.
