Building PVB
Product Classification:
Product Introduction
PVB intermediate film is mainly used for laminated glass, which is a special glass made by sandwiching a layer of PVB film between two pieces of glass and compounding and heating under high pressure. PVB laminated glass is widely used in construction, automobile and other industries due to its multiple functions such as safety, heat preservation, noise proof and ultraviolet isolation. The PVB intermediate film produced by special formula is also widely used in aerospace, military and high-tech industries, such as aircraft, spacecraft, military instruments, solar cell box solar receiver, etc.
