REXI laminated safety glass has sandwiched structure, to put a piece of film of polyvinyl butyral as the main component between two pieces of glass. It is widely used in the construction, automotive and other industries due to its superior functions such as safety, heat preservation, noise control and UV isolation. Most of China laminated safety glass factory uses PVB film.
The interlayer film is a polymer material made of polyvinyl butyral-resin and plastication extrusion by plasticizer 3GO (triethylene glycol octoate). The film’s thickness is generally 0.38mm and 0.76mm, it has good adhesion for inorganic glass, with characteristics of transparent, heat preservation, moisture preservation, high mechanical strength and so on.
The film produced with special formulations are also widely used in aerospace, military and high-tech industries, such as aircraft, spacecraft, military equipment, solar cells and solar receivers, etc.
Laminated safety glass price is decided by the film to some extent.
Security: Under the external impact, due to the absorption of the elastic role of the film layer, it can prevent the penetration of the impact. Even if broken, it only produces spider-net-like cracks, the debris are firmly adhered to the film layer, and will not shed and fall off causing harm, the broken glass can still be used until replaced.
Anti-theft: It is very tough, even if the thieves crack it, the film layer will firmly adhered, maintaining the integrity so the thieves still cannot enter the room. It can be installed instead of fence, not only helps us save money, but also make a beautiful look and get rid of the feeling of prison.
Sound-proof: The film has a damping effect on the sound waves, it can effectively inhibit the spread of noise, especially for buildings near airports, railway stations, downtown and side of roads, after the installation, the sound insulation effect is very obvious.
Anti-UV performance: The film can absorb more than 99% of ultraviolet rays, thereby it can protect the indoor furniture, plastic products, textiles, carpets, works of art, antiquities or other stuff from color fading and aging caused by ultraviolet radiation.
Energy-saving: The film can effectively reduce the solar light transmittance. And glass lamination using dark color low transmittance film has better performance at energy-saving than regular film of the same thickness. At present, China laminated safety glass manufacturers can produce product with a variety of colors.
