Title (EN) THERMALLY STABLE RIGID FOAMS AND METHODS OF MAKING SAME
(FR) MOUSSES RIGIDES THERMIQUEMENT STABLES ET LEURS PROCÉDÉS DE FABRICATION
Abstract: front page image
(EN)The presently disclosed technology provides a composition and method for producing a thermally stable, rigid polyurethane and/or polyisocyanurate foam by reducing or eliminating the presence of alkali metal components and/or alkali earth metal components, thereby producing a foam, which under fire conditions, will at least maintain its volume or intumesce or not reduce its volume by more than about 30%. The presently disclosed technology allows for a reduction in alkali and/or alkali earth metal components in foams that meet current standards with reduced fire retardant loadings. The presently disclosed technology further provides foams with lower alkali and/or alkali earth metal components which may be made to increase in volume under fire conditions.
(FR)La présente invention concerne une composition et un procédé de production d'une mousse de polyuréthane et/ou de polyisocyanurate rigide, thermiquement stable, par réduction ou élimination de la présence de constituants de métal alcalin et/ou de constituants de métal alcalino-terreux, ce qui permet de produire une mousse, qui, dans des conditions d'incendie, maintiendra au moins son volume ou gonflera ou ne réduira pas son volume de plus d'environ 30 %. La présente invention permet une réduction des constituants de métal alcalin et/ou alcalino-terreux dans des mousses qui satisfont les normes actuelles avec des charges réduites de retardateur de flamme. La présente invention concerne en outre des mousses ayant moins de constituants de métal alcalin et/ou alcalino-terreux qui peuvent être amenées à augmenter de volume dans des conditions d'incendie.
