~SGP film is ethylene and methyl acrylate copolymer of a kind of
ionic film, containing about 1% of the sodium metal ions, the bond
for the film and glass if the result of the ionic bonding effect,
SGP film and glass bonding force than the compressive strength of
PVB film and glass much higher. Its hardness is **0 times that of
the traditional PVB interlayer material tenacity, strength is 5
times that of the traditional PVB interlayer material tenacity.
