PVB interlayer is a translucent film, a kind of polymer material extruded from polyvinyl butyral resin by plasticizer. The appearance is translucent film, no impurities, smooth surface, certain roughness and good flexibility, good adhesion to inorganic glass, transparent, heat-resistant, cold-resistant, moisture-resistant, high mechanical strength, etc. One of the best bonding materials for the manufacture of laminated and safety glass in the world. Its advantages are safety, anti-theft, explosion-proof, sound insulation and energy saving performance.
PVB interlayer film is mainly used for laminated glass. It is a special glass made by sandwiching a layer of PVB film between two pieces of glass, compounded by high pressure and heated. PVB laminated glass is widely used in construction, automobile and other industries due to its multiple functions such as safety, heat preservation, noise control and UV isolation. The pvb interlayer produced with special formula also has a wide range of applications in aerospace, military and high-tech industries, such as aircraft, spacecraft, military instruments, solar cells, solar receivers, etc.
When subjected to external impact, PVB laminated glass can block the penetration of impact objects due to the effect of the elastic intermediate layer to absorb the impact. Even if the glass is damaged, only fine cracks like spider webs will be generated, and the fragments will be firmly adhered to the intermediate layer. It will not fall off and hurt people, and it can continue to be used until it is replaced.
Laminated glass made of PVB is very tough, even if the thief cracks the glass, the interlayer is firmly adhered to the glass, and it still maintains the integrity, so that the thief cannot enter the room. After installing the laminated glass, the guardrail can be omitted, which is not only cost-effective and beautiful, but also can get rid of the feeling of a cage.
· Structural integrity
Under normal load conditions, the performance of the laminated glass is basically the same as that of the monolithic glass, however, once the glass is broken, the laminated glass obviously maintains its integrity, and very few glass fragments fall.
· Sound insulation
Because PVB film has the function of damping sound waves, PVB laminated glass can effectively inhibit the transmission of noise, especially in the buildings located on both sides of airports, stations, downtown and roads, after the installation of laminated glass, the sound insulation effect is very obvious.
· UV protection
PVB interlayer can absorb more than 99% of ultraviolet rays, thus protecting indoor furniture, plastic products, textiles, carpets, artworks, ancient artifacts or commodities from fading and aging caused by ultraviolet radiation.
· Energy saving
The architectural laminated glass made of PVB interlayer film can effectively reduce the penetration of sunlight. With the same thickness, the laminated glass made of dark low transmittance PVB film has a stronger ability to block heat.
Isolate UV rays
