The invention relates to the preparation of rigid foamed materials containing urethane groups using a mixture of blowing agents of 5 to 50 parts by weight of C3- and/or C4-alkanes and 50 to 95 parts by weight of cyclopentane. The invention also relates to the use of the rigid foamed materials thus prepared as composite elements or for filling hollow spaces during the construction of refrigerators.
L'invention concerne la production de mousses rigides contenant des groupes uréthane au moyen d'un mélange d'agents moussants constitué de 5 à 50 parties en poids d'alcane C¿3? et/ou C¿4? et de 50 à 95 parties en poids de cyclopentane. L'invention concerne également l'utilisation des mousses rigides obtenues selon ce procédé comme éléments de composite ou pour le remplissage d'espaces vides dans la construction de réfrigérateurs.
