PVB film is currently the most widely used interlayer material for architectural glass and automotive glass.

    PVB laminated glass film has good safety, sound insulation, and UV resistance, but PVB has poor water resistance, and it is easy to fall off after long-term wet soaking. SGP film has good edge stability and is not sensitive to moisture. SGP laminated film itself is colorless and translucent, has good weather resistance, and is not easy to yellow.

    SGP has extremely high strength, and the bearing capacity of SGP laminated glass is twice that of PVB laminated glass of the same thickness; at the same time, under the condition of equal load and equal thickness, the bending deflection of SGP laminated glass is only 1/4 of that of PVB laminated glass.

    The tear strength of the SGP laminated film is 5 times that of the PVB laminated film. Even if the glass is broken, the SGP film can also bond the broken glass to form a temporary structure after the destruction. Its bending deformation is small, and it can withstand a certain amount of load without the whole piece falling.

    The production process of SGP is close to that of PVB, and the equipment can be used in common with PVB production equipment. The higher price is the reason for the slower market acceptance of SGP.
