Abstract:
Embodiments of the invention provide for low density flexible polyurethane foams are reaction products of reaction systems including at least one polyol and at least one isocyanate including at least 50% by weight of an MDI based isocyanate. The flexible polyurethane foam has a density of less than about 33 kg/m3 as determined according to ASTM D 3574-01, a tear strength of more than about 160 N/m as determined according to NBR 8515:2003 and a resiliency of at least 45% as measured according to ASTM D-3574-H.
