Nomex is a meta-aramid, aramid 1313. It is characterized by good heat resistance and high strength. Its material properties can remain stable for a long time at a temperature of 250°C. Nomex paper produced by DuPont is an aromatic polyamide, often called aramid. The molecular structure of this material is particularly stable. The excellent performance of Nomex is derived from this. It has superior high temperature resistance, flame retardancy, Non-toxic, and good electrical and mechanical properties.
Nomex flame-retardant fiber has a limiting oxygen index of 28, has a high decomposition temperature, and will not melt under high temperature conditions. Nomex has good thermal stability. After 100 hours of continuous use at a high temperature of 260°C, its strength can still maintain 65% of its original strength. It can still maintain 50% of its original strength after being used for 7 days at a high temperature of 304°C. Nomex also has excellent chemical resistance, that is, resistance to acids, alkalis, oxidants, and organic solvents. It has excellent radiation resistance and has almost no loss of strength under the irradiation of a certain intensity of ultraviolet rays and Y-rays.
Aramid IIIA is made of 93% Nomex, 5% para-aramid, and 2% carbon fiber. It is divided into white silk and liquid coloring Two kinds of colored silk. Its white silk dyeing has passed the test. It is currently used in industrial flame retardant clothing, arc protection clothing, firefighting clothing, racing clothing, and welding and furnace work clothing.
Among the raw material flame-retardant fabrics produced by the city’s textile industry, Aramid IIIA fabrics can be used. According to customer needs, Nomex fabrics produced by DuPont or domestically produced fabrics can be used. meta-aramid to better achieve the flame retardant properties of the fabric.
