An important point to take into account during the execution of a project that requires glass elements is its degree of safety. This level of safety depends, among other things, on the installation area of the glass element, the possible mechanical loads to which it will be subjected, among other factors. When we talk about safety, laminated or laminated glass is a recommended option to consider. This material stands out compared to other types of glass, because it has a layer or sheet of polyvinyl butyral, which serves as a joining element for the glass layers that make it up.
In this article, we are going to learn more about what this bonding layer is made of, its main characteristics and what applications it has in projects that require protection glass.
PVB, which is called polyvinyl butyral, seen as a material, is a polymer that serves as a bonding layer in the manufacture of laminated glass parts. It is obtained by combining polyvinyl alcohol with butyraldehyde.
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.
