The surface of White Polystyrene Plastic Sheet Light Diffusing presents a soft and delicate matte white, with a silky semi-glossy surface on one side and a special process on the other side to form a micron-level optical diffusion texture. The size and appearance can be customized according to different uses. It is a lightweight diffuse reflective plastic sheet made of high-purity polystyrene as the main base material through precision extrusion molding technology.
White Polystyrene Plastic Sheet Light Diffusing has excellent light transmittance, and the standard light transmittance can reach 80%. It can provide multiple levels of optical transmittance options such as 75%, 70%, 65%, and 60% according to customer needs. Its optical diffuser is evenly distributed, which can achieve high shielding of light source highlights while ensuring that the brightness of the overall lighting system is not lost. It is particularly suitable for application scenarios such as LED light boxes, panel lights, and light guide backplanes that require both light uniformity and brightness. After the light source is introduced into the sheet, it can effectively disperse the concentrated light beam, reduce shadows and glare, thereby improving visual comfort and meeting the illumination distribution requirements of indoor light environment engineering.
Compared with traditional acrylic diffusers, White Polystyrene Plastic Sheet Light Diffusing has significant advantages in impact resistance. Experiments have shown that its impact strength can reach more than 20kJ/m², which is about 300% higher than ordinary PS boards. It is not easy to break and is suitable for a variety of high-frequency assembly and handling environments. Whether it is used for interior decoration panels or lighting shells of public facilities, it can maintain good integrity and damage resistance during long-term use, greatly reducing the frequency of maintenance and replacement, and saving a lot of after-sales and labor costs for the purchaser.
The board surface of White Polystyrene Plastic Sheet Light Diffusing has been designed with a specific optical structure, a concave hexagonal pattern or a conical shading pattern, which can effectively control the uniform glare value below 19. This level is widely used in modern high-standard office lighting and educational lighting systems, which can significantly reduce the eye fatigue of users working under light for a long time. The surface of the sheet forms a multi-angle reflection mechanism to maximize the diffusion of LED hot spots. When used with lamps, it can easily pass the European standard EN 12464-1 for visual comfort.
White Polystyrene Plastic Sheet Light Diffusing uses non-toxic, heavy metal-free environmentally friendly polystyrene resin, and has passed RoHS, REACH and other environmental regulations certification, meeting the strict requirements of the European and American markets for material safety. No harmful solvents are added during the production process, no secondary pollution is generated, and it has good recyclability. The main substances released during the combustion process of the sheet are carbon dioxide and water vapor, which has little impact on the environment. It is a green solution to replace traditional polluting diffusion sheets.
White Polystyrene Plastic Sheet Light Diffusing has excellent physical stability and thermoplastic molding capabilities. It can be processed by CNC cutting, laser engraving, cold bending and hot folding, silk screen spraying and other methods, and is not easy to deform or crack. The standard thickness covers 1.0mm to 3.0mm, and the conventional sizes are 12001200mm and 12202440mm. Special specifications can also be customized according to customer drawings. It is particularly suitable for OEM/ODM lighting equipment manufacturers for diversified design and development, which improves production efficiency while saving mold development costs. It is an ideal optical diffusion material choice for medium and large lighting companies.
White Polystyrene Plastic Sheet Light Diffusing is widely used in commercial light box solutions of international lighting brands such as Philips, and is particularly suitable for installation in airport terminals, shopping mall exterior walls and underground shopping malls. These application scenarios require that the sheet can not only operate stably for a long time, but also effectively hide the lamp beads and improve the clarity of advertising images. By customizing the 65%-75% light transmittance version, the material achieves an ideal balance of light source shielding while evenly scattering light, greatly improving the overall brightness performance of the light box and the visual appeal of the advertisement, and has been used continuously for more than five years in Philips' designated factories.
In the OEM production line of Osram in Germany, this diffuser is mainly used for high-brightness LED panel light projects. Each sheet must pass the UGR≤19 test standard before cutting to ensure that it can be directly used in office buildings, conference rooms, libraries and other places with sensitive visual comfort after assembly. White Polystyrene Plastic Sheet Light Diffusing sheets provide long life, anti-deformation, and stable light efficiency performance guarantees in such projects, which not only reduces quality complaints from lamp manufacturers, but also helps end customers get a consistent lighting experience.
GE Healthcare uses this product as a light source protection cover and diffusion layer in medical imaging equipment. Since hospitals have extremely high requirements for material stability and environmental protection, White Polystyrene Plastic Sheet Light Diffusing mainly reflects its long-term performance of no odor, resistance to washing, and no yellowing in such high-end applications. Especially in the indicator lights or display modules of X-ray, MRI and other equipment, this product can effectively reduce direct light stimulation, realize soft light prompt function, and has good compatibility with medical-grade electrical components, ensuring the overall operation safety of the equipment and the visual experience of doctors and patients.
In IKEA's home lighting series, White Polystyrene Plastic Sheet Light Diffusing is the core diffusion material for ceiling lamps, wall lamps and other lighting covers. It is especially suitable for bedrooms and children's rooms, which have high requirements for glare control and color temperature and softness. White Polystyrene Plastic Sheet Light Diffusing provides multiple advantages such as cuttable, lightweight and non-toxic. With the LED modules used in large quantities by IKEA, the terminal lamps not only achieve Nordic minimalist appearance design, but also have uniform and soft diffuse light effect. It is one of the preferred diffusion materials for affordable and efficient home lighting.
In the guide system of ExxonMobil's large-scale international energy exhibition, the diffuser is used in the backlit signboard and guidance system to ensure that the booth information is clear and readable and not disturbed by ambient light. The customized texture structure ensures consistent light reflection effect when observed from different angles, thereby helping visitors to quickly locate and identify information content. The material is highly stable and will not deform or turn yellow even when operated at high brightness for many consecutive days, which greatly improves the exhibition operation efficiency and the brand's professional image.
