Abstract:
The invention relates to compositions of glycidyl ester used as a stabilizer in polyurethane foams formulations having a good resistance to hydrolysis, improved damping with equivalent or improved physical properties, and high sound absorption capacity. The mono or poly-carboxylic acids glycidyl ester is used in amount of 0.1 to 10 weight % over the polyester polyol resin.
