Soundproof PVB Film Interlayer for Laminated Glass
Our PVB Acoustic Film offers outstanding benefits, including excellent noise reduction, enhanced safety, and durability. It effectively minimizes sound transmission, creating a quieter and more comfortable environment. The film also improves the impact resistance of laminated glass, adding an extra layer of protection. Its robust design, with superior bonding and tear resistance, ensures long-lasting performance across various applications.
PVB Acoustic Film Description
Introducing our advanced PVB Acoustic Film, specially engineered to deliver superior soundproofing for a variety of applications. Our film features an innovative three-layer composite structure:
Middle Layer: The central film is manufactured from a unique raw material specifically designed to block sound transmission. It provides excellent noise damping properties, effectively minimizing sound penetration and enhancing acoustic comfort.
Outer Layers: The outer layers are composed of a specially structured PVB resin. This advanced resin formulation significantly enhances the bonding strength and tear resistance of the PVB Acoustic Film, making it robust and durable.
When integrated into laminated glass, our PVB Acoustic Film significantly enhances impact resistance, ensuring long-lasting performance and reliability in demanding environments.
Performance Certification:
The PVB Acoustic Film has been rigorously tested by the National Building Materials Testing Center for its sound insulation performance, specifically the sound reduction index (Rw (C; Ctr)). According to the test report, the PVB Acoustic Film achieves a maximum Rw value of 37 dB and a minimum of 34 dB.
