Outdoor-Grade PC Diffusion Sheet: 1mm Thick Translucent Polycarbonate

This 1mm-thick translucent polycarbonate (PC) light diffusion sheet is a high-performance optical material meticulously engineered for outdoor lighting and advertising signage. Its core advantage lies in a light transmission rate of up to 80%—far exceeding the approximately 20% transmission rate of standard milky-white PC sheets. Thanks to uniformly distributed optical diffusion particles within the material, light undergoes refraction, reflection, and scattering as it passes through, seamlessly transforming harsh point or linear light sources into soft, uniform area lighting. This diffuse light effect eliminates dark spots and prevents the light source from casting a direct image, creating a comfortable visual experience that is "translucent yet opaque," resulting in a crystal-clear, realistic, and aesthetically pleasing lighting effect.

Regarding adaptability to harsh outdoor environments, the sheet demonstrates exceptional weather resistance and physical strength. It maintains structural stability without deformation or degradation across extreme temperatures ranging from -40°C to 120°C. Additionally, the surface can be treated with an optional UV-resistant coating that blocks over 99% of ultraviolet rays, preventing aging and yellowing caused by prolonged sun exposure and ensuring high light transmission even after more than a decade of outdoor use. Its impact resistance is outstanding; it withstands strong winds and is lightweight, significantly reducing installation complexity and structural load-bearing costs.

In terms of safety and application, the sheet is a flame-retardant, eco-friendly material that emits no toxic gases during combustion, thereby ensuring the safety of public facilities. Thanks to its excellent all-around performance, it is widely used in outdoor billboards, LED displays, lightboxes for subway and bus stations, natural lighting skylights, and stage special effects. Delivering superior optical performance by day and night, it is an ideal and indispensable choice for modern outdoor lighting projects.
