Heat-strengthened glass, has the same production method as tempered glass, that is to heat up the glass to softening point nearby, and then rapidly cooled down. During the instant cooling procession, cooling rate caused by wind pressure is lower than tempered glass, therefore, temperature variance between intermediate level and superficial level is relatively smaller and stress is relatively smaller accordingly.
 

Feature

• High intensity: Mechanical strength of heat-strengthened glass is as 1.5-2 times as annealed glass.
• Thermal ability: Variance of the heat-strengthened glass heat resistant is as high as 130°C-170°C, which can fully withstand the impact of temperature difference on middle glass and side glass from intense solar, keeping unbroken.
• Prevention from self destruction: Compared with tempered glass, self destruction would not happen to heat-strengthened glass, which is its biggest advantage.
• Stress residue: When heat-strengthened glass is destructed, its special stress structure enables fragments maintain in the frame, unlike tempered glass that will become particle falling down. This advantage of heat-strengthened glass saves much time when doing replacement of glass. And after destructed, every fragment remains a certain residual stress. Therefore, it still has anti-impact ability to some extent.
• High degree of plainness: compared with tempered glass, because of small cooling stress and slow cooling rate during production, degree of plainness of heat-strengthened
