The high level of protection synonymous with NOMEX® fibers is engineered into their molecular structure. It does not come from chemical treatment. This means that the heat and flame resistance of garments made of NOMEX® is inherent and permanent, and does not wear or wash out. You can count on the protective performance of NOMEX® to last the life of a garment. Nomex® IIIA is widely used for clothing for the military, fire fighters, auto racers and industrial workers. Nomex® IIIA is suitable for most applications except welding.

The Importance of KEVLAR®

One of the most effective ways to reduce second and third degree skin burns is to make sure that the barrier of protective clothing between the heat source and skin remains intact during exposure. At DuPont this is called 'non-break-open protection' or, 'break-open resistance'. Unlike conventional fibers, NOMEX® consolidates and thickens when exposed to a high temperature heat source. The presence of KEVLAR® in the fiber blend then prevents this swollen fabric from breaking open. Well engineered fabrics made from one of the NOMEX® family of fibers which also contain KEVLAR® maintain the all important protective barrier even during exposure to extremely high temperatures.
