PVB is the abbreviation of Polyvinyl Butyral.PVB film is made from PVB resin and plasticizer. It is a non-toxic and smell-free soft sheet material with thickness between 0.2mm~2mm, the best material for the interlayer of safety glass. The process of PVB films is complicated andonly veral international companies just like Dupont(US),Solutia(US) and Sekisui (Japan) owned. In China, the PVB film market has been long dominated by foreign companies. With the increasing demand of safety laminated glass, the market for PVB films is also increasing. Laminated glass not only has a good optical nature,but also resistant to penetration,ultraviolet etc. It is widely used in areas such as defense industry, Transportation construction,etc.
Product characteristics: 
      The PVB interlayer withstands penetration from impact. Even if the glass cracks, it will only have web-shaped similar fine cracks, and splinters will adhere to the interlayer and not scatter. In such still can be used until it is replaced.

    ·Penetration resistance
       Compared with other glass products, laminated glass produced by PVB membrane has protective effect on human body and property. The standard "two clip a" glass can withstand the penetration of the general impact; even if the damage is strong, the gap is very small. Once broken,   the    middle layer still plays a protective role on the building until the glass is replaced.

    ·Sound Control
       PVB interlayer in laminated safety glass has a resisting effect on sound waves. PVB laminated glass can effectively prevent the spread of noise especially those located in airports, railway

       PVB interlayer can filter 99 % of the ultra-violet light thereby helping to avoid direct sunlight and delaying the aging and fading of interior decoration to prolong its service life.。
