Polyvinyl Butyral Film（PVB Film）
ANHUI LIWEI CHEMICAL CO.,LIMITED
[Introduction]
PVB Film is a kind of the laminated glass interlayer, or called PVB interlayer/sheets, it is manufactured commercially by extrusion with PVB resin, plasticizer and additives. PVB film exhibit special characteristics such as transparency, impact resistance, high tensile strength, and elasticity, even if the glass cracks, splinters will adhere to the interlayer and not scatter. These properties make the films and sheets suitable for the manufacture of safety glass. It is primarily used in the production of automotive windshields and the usage of PVB film in building & construction, Additionally PVB film can be applied in photovoltaic modules fields.

Frequently Asked Questions
1.What are the main materials of your PVB film?
The main raw materials are polyvinyl alcohol (PVA), plasticizer, etc. PVB resin is generated by condensation reaction, and then PVB film is made through drying, winding and other steps.
2. What are the specifications of PVB film?
There are many specifications of PVB film, the common ones include 0.38mm, 0.76mm, 1.14mm, 1.52mm, etc. PVB films of different specifications are suitable for different application scenarios and needs.
3. What are the advantages of PVB film?
PVB film has many advantages, including high transparency, heat resistance, cold resistance, high mechanical strength, good adhesion, etc. In addition, it can absorb impact energy, reduce the splash of broken pieces, and has excellent safety performance. At the same time, PVB film also has the properties of sound insulation, heat insulation, and UV protection, and is widely used in various occasions that require high-performance glass.
4. What is the storage condition of PVB film?
1)The unpacked room temperature film can be stored in an indoor warehouse, to avoid rain and sun, and the storage temperature is preferably below 30°C.
2)ANHUI LIWEI PVB film has been unpacked can be stored in an air-conditioned room(Lamination room) at 18-20°C and 25-30% relative humidity. Because of the PE Separated film, the PVB film will not stick together. When the humidity of the film is too high, it must be restored to a relative humidity of 25-30% before use, and placed under this condition for an appropriate time to restore the moisture on the surface of the PVB film to 0.4-0.6% before it can continue to be used.
5. What should I do if the PVB film I purchased has quality problems?
If the PVB film you purchased has quality problems, please contact our customer service staff immediately. We will handle it for you as soon as possible and provide corresponding after-sales services, including return, exchange, etc.
6. Does your PVB film support customization?
Yes, we support customized services for PVB films, and can customize colors and size, etc. according to the specific needs of customers.
7. Has your factory passed relevant certifications?
Yes, our factory has passed ISO9001 quality management system certification, and other relevant certifications to ensure product quality and safety.
