Patent attributes
A first composition is disclosed that includes a fire-resistant thermoplastic resin. The fire-resistant thermoplastic resin includes 1-20 wt % of an aryl phosphate, includes 1-20 wt % of a phosphate polymer, and 60%-98% of a (meth)acrylic polymer, including units from at least one monomer, wherein the monomer is chosen from methyl methacrylate, acrylic acid, methacrylic acid, acrylic acid esters, methacrylic acid esters, acrylonitrile and maleic anhydride. The first composition may further include a fabric or a composite material that is embedded with the fire-resistant thermoplastic resin. In some instances, the aryl-phosphate and the phosphonate polymer synergistically reduce an effective heat of combustion, a peak heat release, or a flame time as compared to a second composition that contains only one of the aryl phosphate or the phosphonate polymer.
