As a China Acrylic Prismatic Panel Supplier, let me share with you.
Polycarbonate board is abbreviated as PC board, which is made of polycarbonate
polymer using advanced formula and the latest extrusion technology. PC board is
a new type of high-strength, light-transmitting building material, and the best
building material to replace glass and plexiglass. Compared with laminated
glass, tempered glass, and hollow glass, PC board has excellent performance such
as light weight, weather resistance, super strength, flame retardant, and sound
insulation, and has become a popular building decoration material.

Exposure to light sources may impair the performance of the material. In the LED environment, this illumination may come from two directions-the LED light source itself, or it may come from the sun's natural light. This continuous exposure can cause performance to decline over time. Therefore, when selecting the correct materials and formulation materials suitable for LED applications, it is particularly important to stabilize the product with appropriate ultraviolet rays to minimize the impact of this phenomenon.
Polycarbonate offers many ways to do this, including additives and layered films in extruded products.
The selection of materials is very complicated, and many factors must be considered to ensure that the correct solution is provided for LED lighting applications. Polycarbonate is a leading material choice because it effectively solves some of the most difficult challenges in the LED lighting industry. The versatility of the material and the ability to customize characteristics can meet the needs of manufacturers and molders.
Generally speaking, there are two kinds of resins purchased by the board production plant, one is ordinary PC resin, and the other is PC resin containing anti-ultraviolet additives. The selected anti-ultraviolet additives are as large as the following categories:
(1) Salicylic acid esters, such as p-tert-butylphenyl salicylate (TBS).
(2) Benzophenones, such as 2-hydroxy-4-methoxybenzophenone (UV-9); 2-hydroxy-4-methoxy-2'-carboxybenzophenone (UV- 207); 2-hydroxy-4-n-octyloxybenzophenone (UV-531).
(3) Benzotriazoles such as 2-(2'-hydroxy)-3,7,5'-di-tert-butylphenylbenzotriazole (UV-320); 2-(2'-hydroxy-5 '-Tert-octylphenyl)benzotriazole (uV-5411) and so on. PC board is very easy to produce internal stress. Whether the board has internal stress can be tested by carbon tetrachloride soaking and polarized light. The internal stress of the sheet can be eliminated by annealing.
