Sell tempered glass

Tempered glass/toughened glass are made by forming compressive stress on the surface of the glass and heating the glass up to its intenerating temperature and then make the glass uniform cooling quickly. During the process of cooling, the exterior part of the glass is solidified because of the rapid cooling, while the interior part of the glass shrinks because of slow cooling, then forming compressive stress on the surface of the glass and tensile stress inside the glass, thus improving the intensity and heat stability of the glass.
Safety performance: Glass will appearance hurtless obtuse angles when breakage.
Strength performance: Four times more than ordinary glass.
Heat stability performance: Three times more than ordinary glass, could bear the temperature change about **0° C.

Standard: EN ****0; ASTM ***8; BS ***6: ***8; GB ****3.*****5; AS/NZS **8: ***6

Heat strengthened glass adopt the similar process, but the cooling course is longer than tempered glass. So the compressive stress is not so big like tempered glass and the flatness is more perfect.
Safety performance: Not easy to breakage, and could remain in frame when breakage.
Strength performance: Twice than ordinary glass
Heat stability performance: Could resist heat effectively, and avoid heat breakage
Standard: EN*****1; ASTMC *******6

Clear Tempered glass has a very good performance of anti-curve, anti-impact intensity, 3 to 6 times better than normal glass. Tempered glass can afford pressure over *5MPa on the surface. Tempered glass has high stability even under temperature change of ******0 centi-degree, while normal glass can only afford change of *****0 centi-degree. Tempered glass becomes small sand shape if tempered glass is broken under big force, which guarantee safety and less loss.
