High Optical Quality and Design Freedom
Covestro AG, Leverkusen, Germany, has developed an extremely impact-resistant polycarbonate for protecting the eyes of workers. Lenses made of Makrolon 3207 are lightweight and as transparent as glass, thus satisfying the strict requirements of MCR Safety, an American supplier of personal protective equipment.
Lenses made of the Covestro plastic are industrial bullet-resistant and passed tests with 45 gram solid steel bullets fired at the lenses at speeds of 150 until 400 feet per second. Such extreme test conditions are necessary in order to cover all of the loads that could possibly occur during routine work and lead to eye injuries: falling or flying objects, sparks, metal slivers, wood chips, nails or contact with harmful substances. Another advantage of Makrolon 3207 is the high design freedom. This allows for thinner lenses and thus greater comfort with lower production costs.
The Crews Glasses and US Safety series of safety glasses and face shields from MCR Safety are also certified according to the American ANSI Z871.1 standard. MCR Safety has developed its new USS Defense safety glasses primarily for the tightened product safety laws in Asia, where the glasses are also produced.
