Thermochromic PVB Glass Interlayer Film 0.38mm-1.52mm with 25°C-28°C Temperature Response for Smart Buildings

Westglass High-Strength Thermochromic PVB Film is engineered with 80% high-purity polyvinyl butyral resin and photothermal-responsive nanomaterials for smart safety glazing systems. Using 25°C as baseline, it achieves dynamic switching between high-transparency and shaded states through thermally reversible molecular changes, while maintaining strong adhesion, explosion resistance, and noise reduction properties.

Through 120°C-140°C high-temperature lamination, it forms a "glass-PVB-glass" composite structure delivering temperature-adaptive color change, all-weather safety protection, broadband noise blocking, and dynamic energy regulation.
