JH tempered glass is a type of glass with even compressive stress on the surface which is made by heating float glass to nearly softening point and then cooling it down rapidly by air. During the instant cooling process, the exterior of glass is solidified due to rapid cooling while the interior of the glass is cooled down relatively slowly. The process will bring the glass surface compressive stress and the interior tensile stress which can improve the mechanical strength of glass by germination and result in good thermal stability. Tempered glass is one of two kinds of safety glass regularly used in applications in which standard glass could pose a potential danger.  Tempered glass is four to five times stronger than standard glass and does not break into sharp shards when it fails. 

 Now, tempered glass is becoming more and more popular in the world. As we all know, tempered glass is a kind of safety glass. Besides, along with the continuous renewal of products and the processing technology, the application scope of toughened glass has become wider and wider.
