Impact strength is perhaps the most important of the many features of polycarbonate sheet. It is 250 times stronger than glass, and 30-40 times stronger than acrylic. Whether it is used as window glazing, machine guards or in signage, it is virtually unbreakable. Design versatility allows polycarbonate sheet to be used in many ways. It can be vacuum formed and painted into high strength outdoor illumination signs. It can be cold bent on site for curved architectural glazing or it can be cut and shaped for guarding or for glazing applications where there is a potential for glass breakage.
