Abstract: A flame-retardant composition is described comprising a mixture of a water dispersible organic polymer; and a water dispersible derivative of an unsaturated dicarboxylic acid or anhydride thereof. The water dispersible derivative typically has a solubility in a 0.1 N aqueous solution of NaOH at 25°C of at least 25 g/liter. Also described is a flame-retardant composition comprising the mixture described dispersed in an aqueous carrier and method of making a flame-retardant composition.

Abstract: Provided is a multilayer thermal insulator and related method that use a non-woven core layer comprising non-meltable and flame-resistant polymeric fibers. One or more scrims are disposed on the opposing major surfaces of the non-woven core layer, and a peripheral edge of the one or more scrims is either edge sealed or capable of being edge sealed to substantially encapsulate the non-woven core layer within the one or more scrims. Optionally, a binder is provided on the scrims or non-woven core layer to facilitate edge sealing. The provided insulators are essentially dust-free and capable of passing stringent flammability standards.

Abstract: A nonwoven fibrous web includes a flame retardant nonwoven fabric coated with a fire retardant, wherein the fire retardant comprises ammonium polyphosphate or alkali metal silicate; and wherein the flame retardant nonwoven fabric has a first major surface and an opposed second major surface; a first nonwoven fabric covering at least a portion of the first major surface; and a second nonwoven fabric covering at least a portion of the second major surface. The first and second nonwoven fabrics each comprise oxidized polyacrylonitrile fibers and optional reinforcing fibers.

Abstract: The provided articles and methods use a non-woven fibrous web containing 60-100 wt% of oxidized polyacrylonitrile fibers; and 0-40 wt% of reinforcing fibers having outer surfaces comprised of a polymer with a melting temperature of from 100°C to 300°C. The non-woven fibrous web has an average bulk density of from 15 kg/m 3 to 50 kg/m 3 , with the plurality of fibers substantially entangled along directions perpendicular to a major surface of the non-woven fibrous web. Optionally, the oxidized polyacrylonitrile fibers can have a crimped configuration. Advantageously, these articles can display a combination of low thermal conductivity, high tensile strength, and flame resistance.
