2、Strength for resistance to impact：can withstand 1040g steel ball impact at lm height without broken.
3、Bending strength:can reach 200Mpa.
4、Optical performance: lhere is no change during tempering process on glass.
5、Stability for resistance to heat: there is no broken tested under condition of watering melted lead (3270C )onto glass that is under normal temperature.Heating tempered glass to 2000C and then putting into 250C water,there is no broken.
