THE HISTORY OF LAMINATED GLASS(LAMINATING INTERLAYER)
1906, Englishman used a kind of celluloid or other plastic thin film between two glasses to make laminated glass.
1916, Some glass laminating manufacturer used glue and celluloid together to make laminated glass.
1917, Some glass laminating manufacturer used glue, varnish and celluloid together to make laminated glass.
1920, Some glass laminate manufacturer used cellulose ester to make laminated glass.
1938, Some glass laminate manufacturer used acrylate monomer to make laminated glass.
1941, Some laminated glass manufacturer used Vinyl resin film to make laminated glass.
Not long later, One kind of Vinyl resin film dominated the glass laminating interlayers, the film is polyvinyl butyral film.
Later on, the polyvinyl butyral film, PVB Film, has been modified for mechanical properties, temperature resistance properties, light resistance properties.
Some PVB FILM is highly advanced modified and used a new name, like SGP FILM, one kind of PVB FILM modified by DUPONT.
In the early of 21 century, EVA FILM, ethylene vinyl acetate, is used to make laminated glass. EVA Film is easy to processed in simple laminating machine and plays a important roll in laminated glass interlayer market. And EVA Film has been modified in mechanical properties, temperature resistance properties, light resistance properties. Some type of EVA FILM (eg. CNC-FORCE) can be used to replace PVB FILM in architectural laminated glass both indoor and outdoor.
