What is S-LEC™ PVB interlayer?

PVB interlayer is a film consisting of PVB (polyvinyl butyral) as the main raw material and is used to be laminated between two glass panes at high temperature and pressured by an autoclave to mainly prevent the glass from shattering.
Our PVB interlayer, S-LEC™ film, is widely adopted all over the world to improve the performance of laminated glass and is widely adopted all over the world in automotive and architectural glass.


We offer various PVB interlayer performances like solar control, design, adaptability of Head-up Display(HUD), acoustic, safety, security, and UV blocking.
