Nomex is a trademark for a flame-resistant meta-aramid developed by Dupont. Nomex has good thermal, chemical, and radiation resistance for a polymer material. For example, the firefighters’ suits are made of Nomex because of their resistance to fire and chemicals. But this also causes Nomex to have a poorer strength and a lower
resistance to heat than Kevlar.
NOMEX fiber has excellent high-temperature resistance, flame retardancy, good spinnability and dimensional stability, and good mechanical properties. It is made into filter bags in the industry and can withstand high-temperature smoke at 200 ℃. The instantaneous temperature can reach 250℃, widely used in the high-temperature flue gas dust removal project of cement rotary kiln head and kiln tail.
Use NOMEX fiber to woven fabric. Add 2% anti-static and 5% aramid 1414 to make NOMEX3A flame-retardant fabric, which is the best choice for work clothes in the petroleum industry.
