Main destinations:
Automotive glass: A must-have for the windshield—shatters without scattering debris, ensuring passenger safety.
Architectural glass: curtain walls, shop windows, and bank counters—providing both anti-theft protection and resistance to typhoons.
Photovoltaic modules: The encapsulant material of double-glass modules is resistant to aging, thereby extending the service life of solar panels.
Specification basics: Common thicknesses include 0.38 mm, 0.76 mm, and 1.14 mm, among others; multiple layers can be stacked for use.
Why can it both save lives and conserve energy?
1. Safety and Shatter Resistance: When glass is struck and breaks, the film holds the fragments in place, preventing them from scattering and causing injury, while also providing resistance to penetration.
2. Sound and thermal insulation:
Sound insulation: It impedes sound waves, reducing external noise, making it suitable for airports and roadside buildings.
Heat insulation: Blocks over 99% of ultraviolet rays, reduces air-conditioning energy consumption, and protects interior trim from fading.
3. Excellent weather resistance: It operates reliably across a temperature range of –40°C to +80°C and is resistant to delamination even in humid conditions.
