摘要:
Described is a method for using a trialkyl phosphate as a smoke suppressant in a polyurethane foam. The trialkyl phosphate having at least one alkyl group with two carbon atoms is included in the polyurethane foam, which has an absence of halogenated flame retardants.
摘要:
A panel with fire barrier comprises: a metal facing; an insulating foam layer; and at least one fire barrier layer between the metal facing and the foam layer, the fire barrier layer(s) comprising at least one of porous silica; hollow glass microspheres; glass fibres; an inorganic ceramifying composition; a dispersion in a polyurethane polymer matrix or polyurethane/polyisocyanurate polymer matrix or polyurethane/polyurea polymer matrix of expandable graphite. A panel arrangement with fire barrier material in the joint regions between panels, methods of forming the panel and panel arrangement, fire barrier compositions, and reactants for forming the fire barrier compositions are also described.
