Title (EN) A METHOD FOR THE MANUFACTURE OF MONOCOMPONENT POLYURETHANE FOAM
(FR) METHODE DE FABRICATION DE MOUSSE DE POLYURETHANE A UN COMPOSANT
Abstract: front page image
(EN)Monocomponent polyurethane foam is prepared by adding to a pressure container which contains the pre-polymer of polyol and excess of polyisocyanate together with blowing and propelling agent shortly before use an activator which is an organic hydroxy compound with a molecular weight lower than 200 and at least two primary hydroxyl groups or a mixture of such hydroxy compounds which is liquid at 20 C. The activator can be added from a pressure container in which it is present under a gas pressure higher than the pressure in the container with the pre-polymer. A packing of activator consists of a pressure container in which the activator is present under a pressure of an inert gas of at least 5 atmospheres.
(FR)Mousse de polyurethane a un composant preparee en ajoutant a un recipient sous pression contenant le pre-polymere de polyol et un excedent de polyisocyanate avec un agent gonflant et propulseur, juste avant l"emploi, un activateur qui est un compose organique hydroxy avec un poids moleculaire inferieur a 200 et au moins deux groupes primaires hydroxyles ou un melange de ces composes hydroxy qui est liquide a 20 C. L"activateur peut etre ajoute a partir d"un recipient sous pression dans lequel il se trouve a une pression de gaz plus elevee que celle regnant a l"interieur du recipient contenant le pre-polymere. Un emballage d"activateur consiste en un recipient sous pression a l"interieur duquel se trouve l"activateur sous une pression d"un gaz inerte d"au moins 5 atmospheres.
