Laminated glass is made up of two or more pieces of glass with one or more layers of organic polymer interlayer film between them. After a special high-temperature pre-pressing (or vacuum) and high-temperature and high-pressure process, the glass and the interlayer are made permanent. Composite glass products bonded together.
Commonly used interlayer films for laminated glass are: PVB, SGP, EVA, PU, etc.
In addition, there are some special ones such as color interlayer laminated glass, SGX type printed interlayer laminated glass, XIR type LOW-E interlayer laminated glass, etc. Built-in decorative parts (metal mesh, metal plate, etc.) laminated glass, embedded PET material laminated glass and other decorative and functional laminated glass.

According to the different melting points of the interlayer film, it can be divided into: low temperature laminated glass, high temperature laminated glass, and hollow glass;
According to the different materials in the middle, it can be divided into: paper, cloth, plant, wire, silk, metal wire, etc.;
According to the different bonding methods between the laminated layers, it can be divided into: mixed laminated glass, dry laminated glass, and hollow laminated glass;
According to the different types of laminated layers, it can be divided into: general laminated glass and bulletproof glass.
