Flat / Bent Tempered Glass,toughened glass Toughened glass is manufactured through cooling the surface of glasses rapidly and making the compressive stress distribute in the surface of glasses and the tensile stress in the central layer when the sheet glass is heated near the softening point. Because the tensile stress produced by the powerful and even compressive stress is counteracted by the powerful compressive stress of glasses, the safety of glasses is improved. The strength of toughened glass is about eight times of that of the common glasses, i.e. more than 95 Pa. If met with by powerful external force, the toughened glasses will be broken into particles as small as bean. Thus, its harm can be reduced. Toughened glasses can be widely applied to building decoration, furniture, vehicles and vessels.
