New flame retardant fabric at Techtextil
Gulfeng is lighter, thinner and more flexible than other flame-retardant materials consisting of glass fiber, m-aramid and p-aramid or Ox-PAN felt. The paper variant is 0.06 mm thick and weighs 60 g/m² - it looks and feels like normal paper. In addition, the material can be knitted or woven into a soft fabric and felted into flexible mats. This variety makes it suitable for batteries as well as bed linen or bus seats.
Despite its low thickness, the material does not lose its flame retardant properties and serves as a flame barrier. A fire cannot spread or ignite surrounding flammable materials. To achieve this, Toray combines thermoplastic polyphenylene sulfide (PPS) with oxidized polyacrylonitrile fibers (Ox-PAN). When a flame heats the material to 285°C, the PPS fibers begin to melt and form a thin membrane around the Ox-PAN fibers. These absorb heat and oxidize, creating a completely closed barrier against the flames.
At the Techtextil, Toray will also display a range of other technical textiles, including Axtar polyester fleece and an LCP fiber called Siveras.
