Three common interlayers, three process windows
PVB remains the standard interlayer for architectural laminated safety glass. EVA is widely used where moisture resistance and encapsulation are important, including photovoltaic modules. SGP offers higher stiffness and is often selected for structural and facade applications.
What changes on the line
- PVB: needs controlled pre-heating and sufficient residence time to reach a stable bond and clear appearance.
- EVA: crosslinking behaviour depends on the temperature profile, so uniform heating across the full working width is critical.
- SGP: higher stiffness calls for accurate pressure control and careful cooling to avoid internal stress.
Configure the line around your product mix
If your plant runs several interlayer types, choose independently adjustable heating zones and a recipe-based control system. Our non-autoclave laminating lines can be configured for PVB, EVA and SGP, including a 3.3 m x 8 m reference layout.
Send us your glass sizes and interlayer types and we will propose a suitable configuration.
