COMMENTS ON SGP FILM FOR LAMINATED GLASS OVER TRADITIONAL PVB FILM
SGP FILM is specially modified PVB interlayer film.
SGP FILM stands for SENTRY GLASS PLUS.
The special modified properties of SGP FILM are:
1-glass strength after laminated is better than other PVB film 2-stiffness and creep resistance is better than other PVB film 3-temperature performance is better than other PVB film
And SGP FILM can meet the requirements of automotive safety laminated glass: 1-impact resistance from external objects.
2-ensure minimal head trauma for a passenger that strikes the windshield. 3-other safety consideration.
SGP FILM plays good at following test:
2-three point bending test
3-post glass breakage
4-temperature stability best
SGP FILM demonstrates significant structural performance advantages over traditional PVB interlayer film world.
But some CHINA PVB MANUFACTUERS is keeping making progess in modification of PVB FILM properties.
The properties of PVB Film in China is advanced modified in those years. And EVA Film in China makes great progress in structural performance proterties to replace PVB FlILM in some external application.
