4. Specificity and differentiation of interlayer films
All interlayer films used in the manufacture of laminated glass are thermoplastic polymers. They differ from one another in their mechanical behavior . In general, they exhibit elastic, viscoelastic or viscous behavior, depending on the temperature at which the glazing is exposed in the building
