Tempered Glass is which heat the superior float glass close to softening point and rapidly cool in glass surface, make the compression stress distribute in the glass surface, and expansion stress is in center. Because of the powerful equal compression stress, made the expansion pressure generated by outer stress be canceled by the powerful compression stress,then increase the glass's safety.
Features:
1. Safety ,when broken, it splits into tiny harmless pieces. no injuries to human body.
2. Strong intensity: Heat-strengthened glass is twice as strong as annealed glass of the same thickness, and tem pered glass is about 4 times.
3. Heat stability:It withstands abrupt temperature change of 220 Centigrade.
