What You Should Know About Laminated Glass?

You are a jewellery shop manager, when you call a glass company, they may suggest to you a safety glass type called laminated glass to you for your jewellery showcases, so what is laminated glass?

Laminated glass (LG) is a type of safety glass that holds together when shattered. In the event of breaking, it is held in place by a thin polymer interlayer, typically of polyvinyl butyral(PVB), ethylene-vinyl-acetate (EVA) copolymers, lonoplast polymers with electrically neutral units and ionized groups such as carboxylic acid, cast in place (CIP) liquid resin, or thermoplastic polyurethane (TPU), between its two or more layers of glass to form a “Sandwich glass”. The interlayer, made through heat, pressure or UV, keeps the layers of glass bonded even when broken, and its high strength prevents the glass from breaking up into large sharp pieces, preventing risks from cutting people.   This produces a characteristic “spider web” cracking pattern when the impact is not enough to completely pierce the glass. The thermoset EVA offers a complete cross-linking network in the polymer layers providing extra strength, cushioning and stability with glass panes.

Laminated glass can be used for: architecture, glazing, automobile safety, photovoltaic, UV protection, Artistic expression, and Jewellery shop showcases. We list here LG’s common applications: Windows and doors, exterior storefronts, sound stopping, UV blocking, automobile windshields, skylight glazing, and curtain walls, Call us to discuss with us what type of glass you need.

5. Laminated glass used for Photovoltaic

The laminated glass is used widely for photovoltaic panels in solar power stations. Since photovoltain EVA copolymer layers can be well contact with metal and glass, providing this EVA laminated glass size stability, as well the long-term anti-weathering and good functions against humidity and water,

6. Laminated glass used for UV Protection

The laminated glass itself has thicker glass panes and polymer interlayers, and most polymer layers such as EVA and green glass absorb UV lights, and UV absorbent additives are also added to specific polymer interlayers for UV-absorbing Laminated glass, making it very powerful in UV protection and UV absorbing, It can absorb up to 100% UVA and UVB radiations. A paper disclosed that laminated glass can totally block UVA radiation.

7. Laminated glass used for Artistic expression
