Tempered glass is several times greater than ordinary glass strength, bending strength is 3-5 times that of ordinary glass, impact strength is 5 to 10 times of ordinary glass, but also increase the strength of improved security. The second is the use of safety glass factory, its carrying capacity is increased to improve the fragile nature of the glass door, even glass also showed no acute damage to small fragments of the human body injury greatly reduced. Glass resistant radical quenching thermal properties than ordinary glass 2 to 3 fold increase in general can withstand temperature changes over 150LC, to prevent heat burst had a significant effect. Tempered glass has good thermal stability, can withstand the temperature difference is 3 times that of ordinary glass glass table, can withstand the temperature changes 300 ℃. General life of 15 years, but this depends on your usage. Process Category: Physical and chemical glass glass.
