To simulate the self-diffusion coefficient of gases through PVB polymeric membrane, at first, it is necessary to build a model for the amorphous bulk and match the experimental density of 1. The compressive behavior of PVB under quasi-static and dynamic loadings was exclusively studied [5], [6]. This polymer. 6. 2015) Crushed glass and recycled PVB Laminated safety glass is mechanically cracked, followed by chemical separation in alkali water solution at 60°C and final mechanical brushing of glass residues. PVB decomposed by side group elimination above 260 °C. It is prepared from polyvinyl alcohol by reaction with butyraldehyde. Polyvinyl butyral is used in safety glass interlayers, mainly in car windshields. PVB is a colorless, amorphous thermoplastic resin , which is widely used in technological applications such as automotive laminated glass, paints, and adhesives due to its excellent flexibility, ability to form coatings in the film shape, good adhesion properties, and excellent UV resistance.
