SGP Film

SGP Film


The shear modulus of SGP is more than 50 times that of PVB, and the tear strength of SGP is 5 times that of PVB. When the laminated glass produced by SKG film is stressed, there is basically no slippage between the two pieces of glass. The bearing capacity of two pieces of glass is twice as much as that of PVB laminated glass. Under the same load and thickness, the bending of SGP laminated glass is only 1/4 that of PVB laminated glass.
