What is Nomex?

DuPont Nomex fiber is a product with good comprehensive properties for flame retardant protection systems, and is currently widely used in the international market, especially in petroleum, petrochemical, oil and gas, chemical, paint and other possible Flash-hazardous working conditions, firefighters, racers, U.S. military personnel, and even astronauts use protective clothing made from Nomex flame retardant fabrics.

Why Choose Nomex Flame Retardant Protective Clothing?

Nomex is inherently flame retardant. The fibers themselves are not allowed to burn, which means the protection is permanent. The protection comes from the fiber itself, so it doesn't go away with washing and use. When exposed to flames, Nomex fibers expand and thicken, creating a protective barrier between the heat source and the body. The protective barrier remains in place until the clothing cools, giving people critical protection time to escape. Chemically treated flame retardant fabrics, some chemical additives or chemical treatments are used to provide some degree of flame retardant properties. In flash, chemically treated fabrics rely on a chemical reaction to extinguish the flame, depending on the energy of the flame and the amount of time the fabric is exposed to the flame. The degree of heat transfer and subsequent body combustion increases significantly with time and energy. Together with fabrics, these chemicals form strong fire, hot gas, smoke and tar residues that are harmful to humans.

Nomex consists of 93% Nomex, 5% Kevlar and 2% antistatic fibers.

Nomex? fiber has good flame retardant and thermal insulation properties, and the performance is permanent. Because its fire performance is based on the molecular structure of the fibers, rather than being treated with chemical additives. Nomex? carbon fiber at high temperature of 380 degrees Celsius and thickens, increases the protective barrier between the heat source and human skin, this burning degree is minimized, this tough protective barrier remains soft and elastic before cooling down, To avoid crack damage in high temperature environments, so, the wearer can get precious seconds to escape the fire. Nomex does not melt or drip in heat or flames, and more importantly, dies when it is removed from the source.

Although the initial purchase cost is relatively high, the service life of the clothing is not high. Nomex fibers contain 5% Kelvar? fibers, which have good abrasion and tear strength and typically last three to five years. These features allow the wearer to ensure that his clothing remains intact when exposed to the dangers of flash, arcing and heat without accidental burns.

In addition, Nomex flame retardant protective clothing has good corrosion resistance to a variety of chemicals, and has high corrosion resistance to most hydrocarbons and various organic solvents. The corrosion resistance of Nomex flame retardant protective clothing to the chemicals used in today's industry increases its durability. At the same time, Nomex flame retardant clothing can be washed with organic solvents to remove flammable pollutants on it without affecting the service life.

Nomex fibers contain P140 permanent antistatic fibers for increased safety in work environments where flammable gases and dust may be present.
