Semi Tempered Glass or heat strengthened glass
is made by evenly heating flat glass to approximately 620°C. The ceramic roller transmits glass at a stable speed to ensure an even temperature and optical performance. Heat strengthened glass has similar production process to that of tempered glass, except for a longer chilling duration.
The strength and resistance to temperature changes of heat strengthened glass is two times better
than that of the annealed glass at same thickness.
Heat strengthened glass has the same features of annealed glass like hardness, elongation, polarization
and resistance to etching.
Heat strengthened glass breaks into large pieces. Influencing factors are impact
strength, breaking point and glass temperature.
In comparison with tempered glass, heat strengthened glass is not easily broken spontaneously.
After manufactured, it is impossible to do any of cutting, drilling, grinding, frosting and etching.
