article_snippet.sent: Instead STF hardens upon impact at any temperature, providing protection from penetration by high-speed projectiles and additionally dispersing energy over a larger area. '
article_snippet.sent: This viscosity increases thanks to the subordination of the particles in the liquid structure, therefore the subordination of the particles in the liquid structure form a barrier against an external penetrating factor,' said Karolina Olszewska, who performed tests on STF for Moratex.
article_snippet.sent: The exact composition of STF is known only to Moratex and Moratex inventors at the Military Institute of Armament Technology in Warsaw, but ballistic tests proved Moratex resistance to a wide range of projectiles. '
article_snippet.sent: We have succeeded,' said Deputy Director for Research at the Moratex institute, Marcin Struszczyk.
article_snippet.sent: When hit by a high-speed projectile, a wide area of the STF hardens instantly, causing the usually massive energy to be dispersed away from the wearer's internal organs.
