Patent

CA 2737162

The present invention generally relates to polyurethane foam composition. In one embodiment, the present invention relates to polyurethane foam compositions that have increased and/or improved fire-retardant properties due to the inclusion of one or more liquid and/or solid fire-retardants. In another embodiment, the present invention relates to polyurethane foam compositions that have increased and/or improved fire-retardant properties due to the inclusion of one or more intumescent materials (e.g., expandable graphite (EG)). In still another embodiment, the present invention relates to polyurethane foam compositions that have increased and/or improved fire-retardant properties due to the inclusion of expandable graphite.

La présente invention porte d'une façon générale sur une composition de mousse de polyuréthane. Dans un mode de réalisation, la présente invention porte sur des compositions de mousse de polyuréthane qui ont des propriétés ignifuges accrues et/ou améliorées du fait de l'inclusion d'un ou plusieurs agents ignifuges liquides et/ou solides. Dans un autre mode de réalisation, la présente invention porte sur des compositions de mousse de polyuréthane qui ont des propriétés ignifuges accrues et/ou améliorées du fait de l'inclusion d'une ou plusieurs matières intumescentes (par exemple du graphite expansible (EG)). Dans encore un autre mode de réalisation, la présente invention porte sur des compositions de mousse de polyuréthane qui ont des propriétés ignifuges accrues et/ou améliorées du fait de l'inclusion de graphite expansible.
