High-performance yarns include para-aramids, which are used in industrial yarns and in the security sector. Bulletproof clothing is hugely important in the everyday work of certain professionals. Twaron and Kevlar are common para-aramid trade names.
Twaron is used mainly in industrial yarns, for instance as reinforcement in high-pressure hoses, whereas Kevlar is predominantly used in ballistics. Kevlar is one of the main components in protective vests worn to protect people against fatal injuries if they are faced with an armed attack.
Para-aramids are known for their immense tensile strength, which gives them their high energy absorption capacity. They are also very heat- resistant, easily withstanding temperatures of over 370°C.
