How Is Safety Glass Made?
Making Laminated Glass Laminated glass is a type of safety glass that is found in car windshields and is resistant to complete shattering and penetration. Laminated glass is constructed by taking two pieces of normal glass and adding a layer of flexible adhesive material between them, known as the interlayer, to bond to the glass and prevent it from falling apart when broken. The material used as the interlayer is often polyvinyl butyral, or PVB, which is placed in between the sheets of glass, trimmed to size and then pressed and heated to make the glass stick together. After the initial bonding, the glass goes into a large oven called an autoclave, which finishes the chemical reaction and bonding process of the PVB to the glass. Laminated glass is useful for use in buildings and as security glass, since producing cracks in the surface will not allow one to pass through the glass. Making Tempered Glass Tempered glass is another type of safety glass that is perhaps best known in the win
