Aramid is an artificial synthetic fibre, a polyamide fibre consisting of long chains of smaller molecules. It can withstand high temperatures and is fireproof. The properties of aramid fibres are built in at the molecular level using chemical structures and are not treated with chemicals to achieve fire safety. Their ability to resist high temperatures without melting makes them suitable for use where fire safety is a priority. However, the aramid fibre can be treated to improve other properties, such as water repellency or increased abrasion resistance.
We mainly use the fibre for technical applications. Kevlar and Nomex are examples of aramid fibres manufactured by DuPont. Because of their high strength and ability to resist penetration, they are used in bulletproof vests and helmets, among other things. For example, Nomex is used in protective clothing for firefighters and racing drivers, where high heat resistance and fire safety are important properties.
