It is a polymer that has high durability, adherence and has good mechanical resistance to impacts. It can be transparent, allowing light to pass through, or it can be found in a variety of colors.
As a safety element, it is important because, thanks to these properties, it provides a greater safety factor for glass elements. During an impact that involves breaking the material, this layer holds the pieces together, preventing the spread of sharp parts. Let us remember that being a polymer, it can be deformed without the need to break abruptly as in the case of pure glass. Additionally, this layer collaborates with noise reduction.
These qualities make PVB in laminated glass an indispensable material.
