Laminated glass

Laminated glass is a composite glass product consisting of two  more pieces of glass sandwiched with one  more layers of organic polymer intermediate film. After special high-temperature pre pressing ( vacuuming)  high-temperature  high-pressure processing, the glass  intermediate film are permanently bonded as a whole.

The commonly used laminated glass intermediate films are: PVB, SGP, EVA, PU, etc.

Five characteristics

1. Safety: in case of external impact, because the elastic intermediate layer has the effect of absorbing impact, it can prevent the impactor  penetrating. Even if the glass is damaged, it will only produce fine cracks similar to spider network. Its fragments are firmly adhered to the intermediate layer  will  fall off  hurt people. It can be used until it is replaced.

2. Anti theft: PVB laminated glass is very tough. Even if the thief knocks the glass, the middle layer  the glass are firmly adhered together,  the integrity is still maintained, so that the thief cannot enter the room. After the installation of laminated glass, the guardrail can be saved, which can save money  beauty  get rid of the feeling of cage.

3. Sound insulation: due to the damping function of PVB film to sound waves, PVB laminated glass can effectively inhibit the propagation of noise, especially for buildings located at airports, stations, downtown areas  on both sides of the road after the installation of laminated glass, the sound insulation effect is very obvious.

4. UV protection performance: PVB film can absorb more than 99% UV, thus protecting indoor furniture, plastic products, textiles, carpets, works of art, ancient cultural relics  commodities  fading  aging caused by UV radiation.

5. Energy saving: the laminated glass made of PVB film can effectively reduce the sunlight transmission. With the same thickness, the laminated glass made of PVB film with dark color  low light transmittance has a stronger ability to block heat. At present, laminated glass produced in China has many colors.
