Abstract: The subject disclosure provides a viscoelastic polyurethane foam and a method of forming the viscoelastic polyurethane foam. The viscoelastic polyurethane foam comprises the reaction product of a toluene diisocyanate and an isocyanate reactive component. The isocyanate reactive component comprises a first polyether triol, a second polyether triol, an amino alcohol chain extender, and a hydrolyzable polyether polydimethylsiloxane copolymer. The first polyether triol has a weight-average molecular weight of from 500 to 5,000 g/mol, at least 60 parts by weight ethyleneoxy units, based on the total weight of the first polyether triol, and at least 10% ethyleneoxy end caps. The second polyether triol, which is different from the first polyether triol, has a weight-average molecular weight of from 5,000 to 10,000 g/mol and at least 80% ethyleneoxy end caps.

Abstract: La presente divulgación proporciona una espuma de poliuretano viscoelástica y un método para formar la espuma de poliuretano viscoelástica. La espuma de poliuretano viscoelástica comprende el producto de la reacción de un diisocianato de tolueno y un componente reactivo con el isocianato. El componente reactivo con el isocianato consiste en un primer triol de poliéter, un segundo triol de poliéter y un alargador de cadena aminoalcohol, y un copolímero poliéter polidimetil siloxano hidrolizado. El primer triol de poliéter tiene un peso molecular promedio ponderado desde 500 hasta 5000 g/mol, al menos 60 partes en peso de unidades epilenoxi, con base en el peso total del primer triol de poliéter, y al menos 10% de grupos protectores etilenoxi. El segundo triol de poliéter, que es diferente del primer triol de poliéter, tiene un peso molecular promedio ponderado desde 5000 hasta 10,000 g/mol y al menos 80% de grupos protectores etilenoxi.
