NON-SILICONE SURFACTANTS FOR POLYURETHANE OR POLYISOCYANURATE FOAM CONTAINING HALOGENATED OLEFINS AS BLOWING AGENTS |
摘要 |
The invention provides polyurethane and polyisocyanurate foams and methods for the preparation thereof. More particularly, the invention relates to open-celled, polyurethane and polyisocyanurate foams and methods for their preparation. The foams are characterized by a fine uniform cell structure and little or no foam collapse. The foams are produced with a polyol premix composition which comprises a combination of a hydrohaloolefin blowing agent, a polyol, a surfactant component which comprises a non-silicone surfactant and is substantially absent of a silicone surfactant, and a tertiary amine catalyst.
