SPRAYABLE ELASTOMERIC POLYURETHANE FOAM AND PROCESS FOR ITS PRODUCTION

摘要

The present invention relates to a sprayable elastomeric polyurethane foam made from the reaction product of at least one isocyanate, at least one isocyanate- reactive component and water, optionally in the presence of at least one of blowing agents, surfactants, cross-linking agents, extending agents, pigments, flame retardants, catalysts and fillers, wherein the sprayable elastomeric polyurethane foam has a free rise density of from about 5 lb/ft3 to about 25 lb/ft3, a reactive cream time of from about 10 seconds to about 120 seconds, and an elongation of from about 30% to about 300%.
