    Abstract: Described is a fiber glass mat composition comprising a fiber glass matrix bonded with fire retardant melamine resin binder composition capable of forming a nonwoven mat having at least 27% by weight nitrogen (N) in the dry, but uncured resin. Also described is a method of making a fire retardant nonwoven fiber glass mat comprising the steps of providing an aqueous melamine based resin binder; applying the binder to fiber glass; and recovering a fire retardant fiber glass mat, wherein the mat has at least 27% by weight N in the dry, but uncured resin wherein the ratio of resin in the mat to N content of the resin does not exceed about 0.6.

    Abstract: A new thermoformable nonwoven fibrous mat having properties particularly suited for a facer on insulating gypsum board and the method of making the mat is disclosed. The mat can also be pleated or thermoformed to produce filter elements and preforms for producing a wide range of fiber reinforced composites and laminates. The mat preferably contains a major portion of glass fibers and a minor portion of polyester fibers bound together with up to 35 wt. percent of a cross linked vinyl chloride acrylate copolymer binder having a glass transition temperature as high as about 113 degrees F., preferably about 97 degrees F. The binder also optionally contains about 3-10 wt. percent stearylated melamine.
