For glass assembly in the construction industry, only films with high adhesive strength can increase the lifespan of laminated glass. It is precisely because of this quality that PVB is world-renowned and has become a film used in building glass assembly worldwide.

　　PVB glass interlayer film is a polymer material formed by extrusion of polyvinyl butyral resin with plasticizer DHA. The thickness of PVB glass interlayer film is generally 0.38mm and 0.76mm, which has good adhesion to inorganic glass, transparency, heat resistance, cold resistance, moisture resistance, and high mechanical strength. Laminated glass can be used for hollow glass doors and windows. Ordinary insulating glass generally does not have impact resistance, while insulating glass with laminated glass on one side becomes safety glass. According to different purposes, laminated glass can be divided into flat laminated glass, curved laminated glass, bulletproof glass, anti-theft laminated glass, and decorative laminated glass. PVB film is mainly used for laminated glass, with multiple functions such as safety, insulation, noise control, and UV isolation. It is widely used in industries such as construction and automobiles.

　　Due to its high impact strength and safety in use, laminated glass is suitable for doors, windows, ceilings, floors and partitions in buildings, skylights in industrial factories, shop windows, kindergartens, schools, gyms, private residences, villas, madhouses, banks, jewelry stores, post offices, and other buildings that store valuable items or fragile glass. Laminated glass is often used in schools, airports, hotels, ministerial office buildings and other public facilities, places prone to accidents (french window, glass doors, etc.) and roof skylights.

Laminated glass is widely used in doors and windows, floors, curtain walls, and skylights of buildings. Curved laminated glass can be used for elevating sightseeing elevators and revolving doors in shopping malls and hotels. Bulletproof and anti-theft glass can be used in the business halls of financial enterprises such as banks, securities companies, insurance companies, as well as counters, doors and windows in gold and silver jewelry stores, museums, commercial residential buildings, prisons, and other places.
