Carbon fiber Pyromex®

fire-resistant

This product is produced without additional Bromine/halide compounds, making Pyromex® ideal to meet flame resistance requirements while at the same time fulfilling environment regulations. The Limiting Oxygen Index (LOI) of Pyromex® is 50–60, which is much higher than other organic flame-resistant fibers. Pyromex® is widely used in welding blankets, fleece insulation, and carbon/carbon brake applications. Product Range Filament tow: 312K Crimped staple fiber: 51mm and 65mm, 75mm, 102mm We begin with a high quality polyacrylonitrile (PAN) as a precursor fiber, which is specifically engineered for oxidized PAN Fiber. The PAN precursor is then stretched and tensioned to optimize molecular and structural orientation. On-line quality control of the PAN precursor ensures process continuity and efficiency. The precursor is exposed to heated air, turning it into oxidized polyacrylonitrile fiber (OPF). The fiber can be supplied as tow with 312.000 filaments or staple fiber which is crimped and cut to specified cut lengths.
