Title (EN) POLYURETHANE FOAMS
(FR) MOUSSES DE POLYURETHANE
Abstract:
(EN) The present invention relates to a polyurethane foam composition derived from a reaction mixture comprising: a hydrogenated polydiene diol having a number average molecular weight from 1,000 to 20,000; an aromatic polyisocyanate; a plasticiser; and a blowing agent. Preferably, the polyurethane composition further comprises a tackifying resin. The present invention further relates to a process for preparing the polyurethane foam and to articles containing the polyurethane foam.
(FR) La présente invention concerne une composition de mousse de polyuréthane dérivée d'un mélange de réaction. Cette composition comprend un diol de polydiène hydrogéné présentant un poids moléculaire moyen en nombre compris entre 1000 et 20 000; un polyisocyanate aromatique; un plastifiant; et un agent d'expansion. De préférence, la composition de polyuréthane comprend une résine collante. La présente invention concerne également un procédé pour préparer la mousse de polyuréthane et des articles contenant cette mousse de polyuréthane.
