Abstract: A polyurethane foam article comprises a first lift, a second lift, and a pass-line therebetween. The polyurethane foam article comprises the reaction product of an isocyanate-reactive resin composition, an isocyanate, and an indicator dye in the presence of a blowing agent. The indicator dye imparts a color in the first and second lifts and at the pass-line at a first temperature below a decomposition temperature of the indicator dye. The indicator dye chemically decomposes to impart a change in color in the first and second lifts and at the pass-line at a second temperature which is at or above the decomposition temperature of the indicator dye.

Abstract: Se proveen una espuma de poliuretano y una composición de resina que se pueden usar para formar la espuma de poliuretano. La composición de resina incluye un primer poliol basado en etilendiamina y que tiene aproximadamente óxido de etileno al 100% coronado y presente en una cantidad de aproximadamente 0.3 a alrededor de 15 partes en peso basado en 100 partes en peso de la composición de resina, un segundo poliol y un agente de soplado físico que tiene por lo menos 4 átomos de carbono. La espuma de poliuretano incluye el producto de reacción de un componente de isocianato y la composición de resma comprendiendo el primero y segundo poliol, en presencia del agente de soplado físico. Un método para formar una espuma de poliuretano en un sustrato combina el componente de isocianato y la composición de resina para formar una mezcla de reacción. La mezcla de reacción se aplica en el sustrato para formar la espuma de poliuretano.

Abstract: A rigid polyurethane foam includes the reaction product of a resin composition and an isocyanate composition. The resin composition includes a novolac polyol that has a general chemical structure: In this structure, R is an alkyl or alkylene group and the novolac polyol has an average hydroxyl functionality of from 2 to 30 calculated by dividing the weight average molecular weight of the novolac polyol by the equivalent weight of the novolac polyol. The novolac polyol is present in an amount of from 3 to 65 parts by weight per 100 parts by weight of the resin composition.

Abstract: A polyurethane foam and a resin composition that may be used to form the polyurethane foam are provided. The resin composition includes a first polyol based upon ethylene diamine and having about 100% ethylene oxide capping and present in an amount of from about 0.3 to about 15 parts by weight based on 100 parts by weight of the resin composition, a second polyol, and a physical blowing agent having at least 4 carbon atoms. The polyurethane foam includes the reaction product of an isocyanate component and the resin composition comprising the first and second polyol, in the presence of the physical blowing agent. A method of forming the polyurethane foam on a substrate combines the isocyanate component and the resin composition to form a reaction mixture. The reaction mixture is applied onto the substrate to form the polyurethane foam.
