FLEXIBLE POLYURETHANE FOAM AND USE THEREOF

摘要

A flexible polyurethane foam which has sufficient material properties and is reduced in volatile amine content. The flexible polyurethane foam is effective in improving the working atmosphere in production steps and in reducing the amount of volatile amines to be discharged from products. Also provided are an excellent sheet pad and an excellent sound-absorbing material which comprise the flexible polyurethane foam and are for use in motor vehicles, etc. The flexible polyurethane foam is obtained by bringing a compound selected among compounds represented by the formulae (1) and (2) into contact with a polyol composition containing a polyether polyol which is an alkylene oxide adduct (amine value, 400 to 600 mg-KOH/g; hydroxy value, 350 to 700 mg-KOH/g) and with an organic polyisocyanate together with water. In the formulae, R<1> and R<2> each is hydrogen or (CH)n-NH2 (n is 1 to 3); R<3> to R<6> and R<7> each represents hydrogen or C1-4 alkyl or alkenyl; and k and m each is 1 to 6.
