PVB interlayer film is substantially used in automotive safety glass, making the laminated glass safer, as well as controlling noise and segregating ultraviolet shafts. In addition, it's also extensively used in architectural laminated glass and other fields.

     The common density of PVB interlayer flicks used for laminated glass are0.38 mm,0.76 mm,1.14 mm,1.52 mm; the common extents are 1220 mm, 1540 mm, 1840 mm, 2140 mm, 2440 mm, and the colors are substantially red, unheroic, blue, argentine, Brown, etc.

    There are several advantages to using PVB film. First, after relating two layers of glass, it's safe, heat preservation, UV resistance, noise reduction, cold and heat resistance, humidity resistance, canvas resistance, non-toxic, odorless, non-flammable, and colorful physical parcels are fairly stable. Second, the optic parcels are excellent, the refractive indicator is close to the glass and other accouterments, high light transmission, no yellowing, etc.; in addition, the use process is fairly simple; the product price isn't high.

    Still, it also has some disadvantages, and it needs to be modified and acclimated by the material manufacturer If PVB is to be used in the optoelectronics assiduity. First of all, the cling temperature is too high. For illustration, it's delicate for the TV screen to repel the high temperature of further than 100 degrees Celsius for a long time; secondly, the functional group of PVB and numerous polymer accouterments haven't veritably high cling force, similar to the relating force with PET isn't as good as that of glass. It's imperishable, the relating substrate is picky, and multiple verifications are needed before use.
