One of the most widely used interlayer materials is polyvinyl butyral, or PVB. PVB is a resilient plastic that bonds the glass panes together, creating safety glass that protects against impacts, noise, and ultraviolet rays. PVB was first used in glass in the 1930s, and since then, it has become the standard interlayer material for laminated glass. PVB is produced by reacting polyvinyl alcohol with butyraldehyde, resulting in a transparent and flexible film that can be customized in terms of thickness, color, and properties.
According to Suzhou Xiaoshi website, the thickness of PVB interlayer ranges from 0.38 mm to 1.52 mm. Different thicknesses are suitable for different applications, such as windshield, skylight, balcony, door, window, etc. The thicker the PVB interlayer, the better the sound insulation and impact resistance, but also the higher the weight and cost of the glass. Therefore, choosing the thickness of PVB interlayer requires considering the performance, function, and cost of the glass, to achieve the best effect.
The color of PVB interlayer can also vary from clear to opaque, and from white to black, and even to other colors. The color of PVB interlayer affects the light transmission and aesthetics of the glass. Generally speaking, clear PVB interlayer has the highest light transmission, while opaque PVB interlayer has the lowest. The color of PVB interlayer can also match the design and style of the building or the vehicle, creating a unique and attractive appearance.
In summary, PVB interlayer is a high-quality interlayer material that can improve the safety and functionality of glass, suitable for various applications. Choosing the thickness and color of PVB interlayer requires rational design and calculation based on the purpose and requirements of the glass.
