ARC Flash Boot Covers - ARC Value 6.3 - Nomex - Fire Resistant - Cleanroom ESD - Natural Color - FI-CB939NX-91NT

Nomex® suit fibers and fabrics are similar to nylon and manufactured for use in a cleanroom environment. Fabrics woven of Nomex® fibers are used in applications requiring good textile properties, good dimensional stability and excellent heat resistance. They are used in coated industrial fabrics, aerospace fabrics,  and protective clothing. The Nomex® fabrics have good resistance to many chemicals and are highly resistant to most hydrocarbons and many other organic solvents. Their acid resistance is superior to woven nylon fabrics.   Fabrics woven of Nomex© fibers exhibit good resistance to alkalis at room temperature, but degrade at high temperature.

Nomex® fabrics have a low level of flammability and do not melt or flow at high temperatures. Above 700E°F (370E°C), they will degrade rapidly to a friable char. At the point at which woven nylon fabrics melt (489E°F, 254E°C), fabrics woven of Nomex® fiber retain about 60% of their original strength. The flammability characteristics of fabrics woven of Nomex® fibers do not change with laundering.

Compared to woven nylon fabrics, fabrics woven of Nomex® fiber exhibit a higher resistance to beta and gamma radiation, to X-Rays, and to water or steam at high temperatures. Therefore, Nomex is an excellent candidate for protective industrial apparel, aerospace fabrics, and material requiring radiation resistance.

Nomex®– Chemstat 919 and 487: The fabric is composed of 100% multifilament Nomex® fiber which is inherently flame retardant non-oxidant. Exclusively specified by NASA for its refueling and reloading operations. The cleanroom fabric is used with industries concerned about explosive or high heat environments and require employees to wear clothing resistant to flash flame wherever there is possible exposure to an electric arc flash. Nomex fiber has a low level of flammability but above 700°F (370°C) they will degrade rapidly to a friable char. In contrast to other nylon fabrics which will melt at 489°F (254°C). Nomex is gamma compatible and autoclavable.
