evguard® laminating finterlayer - High temperature behavior - up to a temperature of 240°C

by Folienwerk Wolfen GmbH

LG Samples were tested at IFT Rosenheim according to the standard DIN EN ISO 12543-4 for behavior at high temperature. The samples have been exposed to a temperature of 100°C for 2 hours. None of the specimen showed any kind of failure, bubbles or delamination. To investigate the behavior of glass laminates at temperatures beyond the international standard test DIN EN ISO 12543-4, further tests were carried out. Because evguard® laminating film is a crosslinking material, it behaves differently compared to other laminating films. LG samples were exposed stepwise up to a temperature of 240°C. The test up to at least 200°C was passed without any delamination effects or visual changes. Also at a temperature of 240°C, no delamination was detected, only a slight yellowing was observed.
