Sandwiched glass is a composite glass product consisting of two or more pieces of glass, sandwiched with a layer or multi layer organic polymer intermediate film, after special high temperature prepressure (or vacuum pumping) and high temperature and high pressure processing.           
Commonly used laminated glass intermediate films are: PVB, SGP, EVA, PU and so on.     
      

In addition, there are some special colors such as color interlayer laminated glass, SGX type intermediate film sandwich glass, XIR LOW-E intermediate film sandwich glass, etc. Embedded decorative parts (metal mesh, metal plate, etc.) laminated glass, embedded PET laminated glass and other decorative and functional laminated glass.   
      
Laminated glass, as a safe glass, is broken by the impact of a PVB film sandwiched in the middle of its ordinary glass, and does not produce sharp fragments of the glass after the broken glass. At the same time, its PVB intermediate film has the performance of sound insulation and control of the sun, which makes it a new building material with energy saving and environmental protection. The use of laminated glass can not only cut off the anastomosis noise of 1000 Hz to 2000 hertz, which can penetrate ordinary glass, but it can block over 99% of the ultraviolet and absorption infrared spectra. Quantity. As a new type of building material, the laminated glass will play a great role in the use of safety glass.
