夹层玻璃是一种性能优良的安全玻璃，它是由两片或多片玻璃用透明的聚乙烯醇缩丁醛（PVB）胶片牢固粘结而成，具有透明、高机械强度、耐光耐热、耐寒、隔声、控制阳光等性能。夹层玻璃以其韧性、弹性和粘结性而具有良好的抗冲击性能和破碎时的安全性能。夹层玻璃因其使用功能的要求可以生产不同性能品种的夹层玻璃，如：遮阳和隔热夹层玻璃、隔声夹层玻璃、防弹夹层玻璃、防火夹层玻璃、防爆夹层玻璃、防盗夹层玻璃等等。
Sandwich glass is one kind of safety glass with good performance.It is composed of two or serveral pieces of glass bonded firmly by transparent polyvinyl butyra(PVB) film,featured with transparent, high mechanical strength,good light and heat resistance,cold resistance, sound insulation,sunlight control etc,Laminated glass has good shock resistance and break-ing safety feature due to its good toughness,elasticity and adhesive.Laminated glass with different property can be produced according to different functiion requirement,such as: sunshade and heat insulation laminated glass,sound insulation laminated glass, bulletproof laminated glass,fire proof laminated glass,explosion proof laminated glass,anti-theft laminated glass etc.
