Abstract: A unique combination ofa hydrophilic polyol (A) and a hydrophobic polyol (B) having a terminal ethylene oxide cap are used in a resin composition and a polyurethane system, and are used to form a polyurethane article, such as a polyurethane foam. The hydrophilic polyol (A) is ethylene oxide (EO) rich and the hydrophobic polyol (B) is propylene oxide (PO) rich. The hydrophilic polyol (A) and the hydrophobic polyol (B) are present in the resin composition and the polyurethane system in a weight ratio (A:B) of from 1.5:1 to 20:1. The polyurethane article exhibits excellent comfort for use in vehicle applications, such as automotive and motorcycle seating, due to reduced resonance frequency and reduced peak vibration transmissivity relative to previous polyurethane articles.

Abstract: Una combinación única de un poliol hidrofílico (A) y un poliol hidrofóbico (B) que tienen una protección de óxido de etileno terminal se utilizan en una composición de resma y un sistema de poliuretano, y se utilizan para formar un artículo de poliuretano, tal como una espuma de poliuretano. El poliol hidrofílico (A) es rico en óxido de etileno (EO) y el poliol hidrofóbico (B) es rico en óxido de propileno (PO). El poliol hidrofílico (A) y el poliol hidrofóbico (B) se presentan en la composición de resma y el sistema de poliuretano en una relación en peso (A:B) de 1.5:1 a 20:1. El artículo de poliuretano exhibe excelente confort para el uso en aplicaciones vehiculares, tal como un asiento para automóviles y motocicletas, debido a la frecuencia de resonancia reducida y la transmisividad de vibración máxima con relación a los artículos de poliuretano previos.
