PVB film is a translucent film. It is a polymer material plasticized and extruded by Polyvinyl Butyral resin with Plasticizer. It is currently an adhesive material for manufacturing laminated and reliable glass. At the same time, it is widely used in building curtain walls, shop windows, bank counters, steel furnace screens, and various Bulletproof glass. Automotive grade PVB film is an indispensable raw material for automotive front windshield.
As the largest Pva manufacturer in China, Wanwei has an annual production capacity of 350000 tons of PVA. PVB film relies on the specialized automotive film grade PVA and PVB Resin independently developed and produced by Wanwei Group, using the most advanced production technology and equipment from abroad. The technical level reaches first-class in China, and the gap with foreign products is reduced, gradually replacing imports, in line with the development direction and market demand of the domestic industry.
Relying on the experimental line of automotive grade PVB film developed by Wanwei High tech, Wanwei Bisheng Company has achieved significant breakthroughs in production formula and process stability through technological innovation and independent research and development. Relying on the standardized indicators of Wanwei High tech PVB automotive grade resin process, automotive grade PVB film has entered the stage of mass trial order production. In addition to supplying domestic automotive parts markets, it has also stably supplied regions and countries such as South America.
At the same time, in order to pursue the high-end market of automotive grade PVB film, Wanwei Bisheng has implemented an annual production project of 20000 tons of automotive grade PVB film. The production and use of this production line will break through multiple bottleneck technologies in PVB film production and accelerate the localization process of material supply in the domestic automotive industry.
