Fire-retardant materials should not be confused with fire-resistant materials. A fire resistant material is one which is designed to resist burning and withstand heat. An example of a fire-resistant material is one which is used in bunker gear worn by firefighters to protect them from the flames of a burning building.
Anti-flash gear, also known simply as flash gear, is basic personal protective equipment consisting of a fire-resistant hood and fire-resistant gloves, [1] often made of Nomex. The purpose of anti-flash gear is to provide protection to the head, neck, face and hands from short-duration flame exposure and heat.
Fire-resistant versions of cold-weather clothing are produced and issued as FROG equipment, including: silkweight undershirts and underdrawers (nicknamed "polypro"), designed by Polartec as a mock turtleneck meant to be worn next to skin [3] [4] The Grid Fleece Midweight underwear includes a pullover and pants (in green and coyote brown).

Usually, Kevlar, foam, and plastic are layered and covered with fire retardant materials to accomplish these things. It is important that the fibers are strain-rate sensitive, or become more rigid if struck by an object traveling at high speeds, according to a ballistics engineer working for bomb suit manufacturer HighCom Security .
Aramid fibers, short for aromatic polyamide, are a class of heat-resistant and strong synthetic fibers. They are used in aerospace and military applications, for ballistic-rated body armor fabric and ballistic composites, in marine cordage , marine hull reinforcement, as an asbestos substitute, [ 1 ] and in various lightweight consumer items ...
The Army Combat Shirt (ACS) is a flame-resistant shirt developed and used by the United States Army as a supplementary addition to the Army Combat Uniform (ACU). [3] The ACS is a stand-alone shirt designed specifically for use with Improved Outer Tactical Vest (IOTV) in warm and hot weather instead of the blouse, and was introduced in 2007.
A fire-resistance rating typically means the duration for which a passive fire protection system can withstand a standard fire resistance test. This can be quantified simply as a measure of time, or it may entail other criteria, involving evidence of functionality or fitness for purpose.
Ablative armor is armor which prevents damage through the process of ablation, the removal of material from the surface of an object by vaporization, chipping, or other erosive processes. In contemporary spacecraft, ablative plating is most frequently seen as an ablative heat shield for a vehicle that must enter atmosphere from orbit, such as ...
