Meta Aramid (Nomex) By Foot Thickness:1/4" or the 5mm (3/16 inch)Flame Resistant Felt Nomex (also called meta aramid felt) is a high temperature felt that protects against extreme heat. Nomex works as a flame resistant material using three mechanisms. First, the fibers absorb incoming heat, keeping it away from the wearer. Next, the fibers swell and thicken with heat to fill gaps in the apparel. Finally, the thickening and absorption of heat increases the fabric's insulating properties, offering further protection.
