Composite glass is the collective term for a laminate having at least two glass panes which are in each case connected by means of an adhesive intermediate layer composed of plastic, e.g. by means of a casting resin or a thermoplastic composite film, which is highly tear-resistant and is viscoelastic.
Windscreens of all kinds of vehicles as well as crash-proof glazing or pavement light used in the construction sector are part of the main fields of application.
Other customary intermediate layer materials include ethylene-vinyl acetate (EVA), polyacrylate (PA), poly(methyl methacrylate) (PMMA), polyurethane (PUR), etc.
Recently, scientists in Queensland, Australia have developed composite glass that gives phones an 'unbreakable' screen.
