Laminated glass is made of two or more pieces of glass, sandwiched between a layer or multilayer organic polymer intermediate film, through a special high-temperature pre pressure and high temperature and high pressure treatment, the glass and the intermediate film permanent binding as one of the composite glass products.  

Based on the intermediate film with different melting points, can be divided into: coldsandwich glass, laminated glass, hollow glass at high temperature;

According to the method of adhesion between the interlayer is different, can be divided into: the mixing method of laminated glass, laminated glass, insulating laminated glass dry;

According to the middle clamping materials are different, can be divided into: thepaper clip, clip, clip cloth plant, wire, silk, metal wire clip clip and many other species;

According to the different kinds of sandwich layer, can be divided into generallaminated glass and bulletproof glass.
