Abstract
A thermoformable non-woven material that meets at least one of the UL94 V-0 (2013) flammability standard and the ASTM E84-14 (2014) flammability standard. The material may include charring fiber having a denier per fiber at least about 3 and binding fiber having a denier per fiber between about 1 and about 8. The weight ratio of charring fiber to binding fiber may be between about 2:1 and about 4:1, and the denier per fiber of the charring fiber may be at least about twice the denier per fiber of the binding fiber.
