It can obstruct fire for 90-120 minutes,and when it broken,it keep its primary shape and visibility,the glass broken pieces will not hurt human.It is made by cementing together two or more pieces of transparent glass polyvinyl-butyral (PVB)film,its performances are transparent,high mechanical strength,resistance to fire,heat and coldness,sound insulation,sunshine-control.Because the glass is cemented with the medium layer firmly,when the laminated glass is stroke and broken,the broken oieces cemented on middle PVB film only form radialized crackles,can keep its primary shape and visibility,the glass broken pieces will not hurt human,so it can still be used for a certain time.The laminated glass has fine impact resistance and broken safety performance for its toughness,stickiness and flexibility.
