Characterization of Polyvinyl Butyral and Sentryglas® Polymers Used as Interlayers in Laminated Glass

Abstract

The polymers used as interlayers in the laminated glass support the tensile stresses, keeping the glass fragments fixed in the film and avoiding possible accidents. This article aims to characterize the polymers Polyvinyl Butyral and Sentryglas®, as their physical-chemical and mechanical properties. It may help a laminated glass company located in Bahia to optimize its production process. We tested the samples to Fourier Transform Infrared Spectroscopy (FTIR), Thermogravimetric Analysis (TGA), and Tensile. The results allowed us to characterize the materials technically, comparing them with the data from the sheets provided by their manufacturer. In addition, it has provided the Laminated Glass Factory with data that can reduce costs and improve production.
