STFs are engineered nanomaterials that instantly and reversibly change from a liquid to a solid-like material in response to impact or stress. Using a patented method of integrating STF into high performance, engineered textiles, we create advanced STF-Armor protective equipment that moves with the wearer but reacts instantly to provide protection when it is needed. The thin, lightweight STF-Armor can easily be integrated into PPE for occupations that demand the highest degree of flexibility, dexterity and sensitivity.
STF materials offer proven protection against puncture, impact, stab and ballistic threats. Protective materials with STF were originally developed through a collaboration between the University of Delaware and the United States Army Research Laboratory.
