ATL PVB AUTOMOTIVE Acoustic Series-Jiangsu Aotianli New Material Co., Ltd.

ATL PVB AUTOMOTIVE Acoustic Series

The Automotive Acoustic PVB series Interlayer Film adopts multi-layer damping technology and specialized plasticizer formulations to significantly reduce sound transmission through laminated automotive glass. By enhancing the interlayer's viscoelastic properties, this series effectively dampens vibration and minimizes road noise, engine hum, and wind turbulence. Designed to meet stringent acoustic and safety standards, it ensures a quieter, more comfortable driving experience without sacrificing optical clarity or bonding performance.
