The Influences of Varied Processing Techniques on the Performance of Polyvinyl Butyral and High Reliability of Polyvinyl Butyral-Based Glass-Glass Modules

Abstract

Three different techniques, i.e. one-step lamination, lamination+autoclave and rolling+autoclave, were comparatively studied for the processing of polyvinyl butyral (PVB) film. The influences of different processing techniques on the mechanical performance, the transmittance and the adhesion strength between glass and PVB were investigated. Further, the transmittance of PVB with three different processes before and after damp heat test and UV radiation was measured. The obtained results demonstrate that the employment of the autoclave process is beneficial for the mechanical performance of PVB as well as its adhesion with glass. The on-based modules exhibited high reliability during damp heat and thermal cycle test.
