Brief description of PVB Interlayer Film:
PVB interlayer is a macromolecule material molded by polyviny, butyral resin that is plasticized and extruded by plasticity. Our PVB film with excellent light transparency, heat and cold resistance, elasticity, is well-sticking to inorganic glass and the making of laminated safety glass. Usual thickness specification is between 0.2 mm - 2 mm.
Usage of PVB Film:
PVB interlayer is mainly used in making laminated safety glass. Laminated glass is a special glass which is inserted with PVB film between two layers of common glass, which under high heating temperature and pressure, binds to create a single construction. Because of PVB laminated glass with the function of safety, heat preservation, noise proof, and ultraviolet resistance, etc, it is widely used in areas such as high-rise building and auto. PVB film with special formula is also used in airplane, space flight ware, military instrument, solar battery, solar energy acceptor and so on.
PVB Film Features:
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 case. it still can be used until it is replaced.
Since the laminated glass with QIXUE PVB interlayer is very shock resistant, even if a burglar cracks the glass, the laminated glass can still keep its structure integrity because of the middle-layer adherence tenacity. As such, the laminated glass has much strength to resist shock. It also helps reduce outside visibility
3, Structure Integrality
Performance of laminated glass is the Same as single piece glass under the normal load. however once the glass broke up. laminated glass can keep its structure integrality. little shattered glass dropping down.
4, 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 stations, and busy streets.
PVB interlayer can filter 99 % of the ultraviolet light thereby helping to avoid direct sunlight and delaying the aging and fading of interior decoration to prolong its service life
6, Energy conservation
Laminated safety glass with QIXUE PVB interlayer can provide an outstanding heat-resisting performance and help save energy conscription. When the laminated glass adopts dark PVB interlayer with low-light transmittance, the same thickness has a stronger thermal resistance effect.
Packing of PVB Film:
Every layer Of PVB film roll is separated by PE film and vacuumed by aluminum foil and put into wooden cases. The finished quality-control approved product is enclosed with conformed certification and packing list.
