AI Technical Summary
Existing laminated glazing technologies face challenges in achieving high transparency, low haze, low optical defects, and high dielectric strength while maintaining ease of manufacture and handling, particularly for functional layers that enhance 5G signal penetration and propagation without requiring additional infrastructure.
A biaxially oriented polyester film incorporating specific concentrations and sizes of amorphous silica and spherical methyl silsesquioxane particles, combined with a crystallisable polyester matrix, to achieve low haze, high transparency, and high dielectric strength, with optional electrically conductive layers for enhanced functionality.
The film provides a surprisingly advantageous combination of low haze, high transparency, low optical defects, ease of manufacture, and high dielectric strength, enabling improved 5G signal penetration and propagation without additional infrastructure.
