PVBkalvos
PVBkalvos refers to polyvinyl butyral interlayer film, a key component in the manufacturing of safety glass. This thermoplastic resin is known for its excellent adhesion to glass and its ability to absorb impact energy. When sandwiched between two or more layers of glass, PVB interlayer film creates a laminated structure that offers significant safety advantages over monolithic glass. In the event of breakage, the PVB film holds the fractured glass fragments together, preventing them from scattering and causing injury. This characteristic makes PVB interlayer film crucial for applications where safety is paramount, such as automotive windshields, architectural glazing, and security glass. The thickness and properties of the PVB film can be adjusted to meet specific performance requirements, including acoustic insulation, UV filtering, and resistance to penetration. The manufacturing process involves extruding the PVB resin into thin films, which are then typically laminated with glass under heat and pressure. PVBkalvos are widely used globally due to their effectiveness and versatility in enhancing the safety and functionality of glass products.
