Title (EN) LOW DENSITY POLYURETHANE FOAMS
(FR) MOUSSES POLYURÉTHANE BASSE DENSITÉ
Abstract: front page image
(EN)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.
(FR)Les modes de réalisation de la présente invention ont pour objet des mousses polyuréthane souples basse densité qui sont des produits de réaction de systèmes réactionnels comportant au moins un polyol et au moins un isocyanate comprenant au moins 50 % en poids d'un isocyanate à base de MDI. La mousse polyuréthane souple possède une densité inférieure à environ 33 kg/m3 comme déterminé conformément à ASTM D 3574-01, une résistance à la déchirure supérieure à environ 160 N/m comme déterminé conformément à NBR 8515 : 2003 et une résilience d'au moins 45 % comme mesuré conformément à ASTM D-3574-H.
