The following table indicates the detailed value of light transmission. The clear PC sheet is featured in good light transmission, which will not lessen varying with service time. The chromatic PC sheet is able to obstruct from the strongest part of sunray and soften the permeated ray.
Ultraviolet Resistance:
The surface of Polycarbonate sheet is treated with special anti-ultrviolet technique to ensure the stability of ultraviolet resistance. The product can preserve its innate optical property and good weather ability after long-time service. No speedy aging can be generated by ultraviolet. As indicated in the following table, ultraviolet within 350-bicron wavelengths can hardly penetrate the sun sheet. As a result, Polycarbonate hollow sheet is more applicable for advertising material other than the general buildingmaterial.
