Fire/Heat Resistant Fiber

Zoltek Corporation offers Pyron®, an oxidized PAN fiber that is inherently Fire/Heat Resistant, which makes it an effective heat-blocking and fire barrier material. Pyron is an inherently fire resistant fiber specially suited to improve the performance of flame and heat resistant protective apparel. It has excellent heat insulation properties derived from its heat stabilized polyacrylonitrile chemistry and resultant low thermal conductivity. Pyron liners used in protective apparel have exceptional heat blocking characteristics, which can help reduce an individual’s overall heat stress and provide enhanced protection in flashover situations. Pyron fibers are also durable for reliable service performance as a stand-alone fiber or in blends. Automotive applications: Pyron fiber is uniquely designed to deliver improved heat blocking, fire-barrier, and acoustical insulation performance in aircraft seat and automotive engine compartment applications. As engine compartments become smaller and more crowded, nonwovens incorporating Pyron fibers have demonstrated the ability to meet the ever-increasing need for improved thermal insulation without adding undo weight. Pyron nonwoven fabrics or fabric blends are being used to protect the polyurethane foam used in aircraft seats. Delaying the ignition and burning of the foam can slow the spread of post-crash fires and the release of toxic gases. The company through wholly owned subsidiaries engages in the development, manufacture, and marketing of carbon fibers for various applications. Today Zoltek products are increasing the energy output of wind turbines, creating more fuel-efficient vehicles, and lifting other industries to higher levels of performance.
