Opal White Cast Acrylic Diffuser Sheet is a high-performance light diffuser made by casting process. It is made of high-purity PMMA. The overall surface of the sheet is milky white. The surface process can be selected as "one side frosted, one side smooth" or "one side frosted, one side orange peel", providing diversified solutions for different lighting systems and visual effects.
Opal White Cast Acrylic Diffuser Sheet supports multiple light transmittance options, including 90%, 85%, 80%, 76% and 60%, covering a wide range of application scenarios from high brightness to soft light requirements. Its light transmittance test is based on the ASTM D1003-61 standard to ensure the consistency of the optical performance of each batch of products. For backlight systems that require extremely high brightness, the 90% transmittance model JK-90 can be selected, and the efficiency of typical LED lamps is 88%-90%; for systems that require higher lamp bead shielding, the low transmittance models JK-60 or JK-70 with 76%-80% can be selected. Combined with the orange peel texture structure, it can achieve stronger light diffusion ability and visual comfort.
Opal White Cast Acrylic Diffuser Sheet has excellent LED shielding ability. Even if the lamp bead spacing is 1:1, it can still effectively suppress light spots, hot spots and image ghosting, ensuring that the entire panel emits uniform and soft light. This performance is due to its unique material molecular structure and micro-surface texture treatment, which not only improves the diffusion efficiency, but also reduces the system's dependence on the number of diffusion layers, optimizing the overall lighting design cost. For designs with larger lamp bead spacing, JK-90 can be used to maintain efficient diffusion.
This type of diffuser has excellent processability and is suitable for a variety of manufacturing processes such as cutting, engraving, drilling, and thermoforming. Whether it is laser cut into a round lampshade, CNC engraved with advertising patterns, or hot bent into a curved light box, the material maintains dimensional stability and edge finish, and is not prone to cracking or yellowing. Its high weather resistance and low moisture absorption also make it an ideal choice for long-term installation applications, greatly facilitating the flexible design of OEM and ODM manufacturers.
Opal White Cast Acrylic Diffuser Sheet uses environmentally friendly PMMA raw materials, which are formaldehyde-free, halogen-free, and do not release toxic gases. It complies with international environmental standards such as ROHS and REACH. It is highly recyclable and only produces carbon dioxide and water vapor after incineration, without secondary pollution to the environment. It is particularly suitable for markets such as the EU and North America that have strict requirements on the environmental protection of materials. The surface of the sheet is not easy to adhere to dust, which is easy to clean and maintain for a long time, making it an ideal choice for green lighting projects.
Opal White Cast Acrylic Diffuser Sheet supports comprehensive OEM and ODM services, including size customization, transmittance ratio, surface texture design, brand logo printing and packaging solution adjustment. We can recommend the best model combination according to the needs of customer projects. For backlight panel lights, JK-80 with 1:2 lamp bead spacing can be selected; and for edge light guide light boxes, orange peel JK-70 with Laser LGP technology is recommended to ensure that the overall system efficiency reaches 78%-80%. Perfect customization capabilities and rapid response mechanisms are our core competitiveness in winning customer trust in the field of lighting diffusion materials.
In high-end commercial office buildings, Opal White Cast Acrylic Diffuser Sheet is often used in the internal diffusion layer of embedded LED panel lights to create a bright, soft and flicker-free office lighting environment. Its highly uniform light scattering ability effectively prevents the glare of lamp beads, improving the visual comfort and work efficiency of office workers. A large number of engineering projects, such as the new headquarters of Meta in the United States and the WeWork office space in Germany, have selected such diffusion materials to ensure the unity of efficient energy saving and human-factor light environment design.
In the advertising space backlight system of large shopping malls, Opal White Cast Acrylic Diffuser Sheet has stable luminous uniformity, which is particularly suitable for wide advertising light boxes. It supports 1.5~2 times the spacing between lamp beads, and can still achieve highly consistent image light effect display, perfectly avoiding shadow or bright spot problems. It has been used in large light box projects of Lotte Department Store in South Korea and Dubai MALL, effectively solving the problem of insufficient edge brightness, and is well received by the visual marketing team.
In the flight information display boards and guide light boxes of Singapore Changi Airport and Hamad International Airport in Qatar, Opal White Diffuser Sheet is used to ensure stable output of all-weather light sources. Faced with high-intensity use frequency and extreme climatic conditions, Opal White Cast Acrylic Diffuser Sheet provides excellent thermal stability and UV weather resistance to avoid yellowing or cracking caused by light aging. Its version with a transmittance of up to 90% can also take into account brightness and energy efficiency, and is the preferred supporting material for LED light guide backplanes of smart airport systems.
In the corridor light strip systems of five-star hotels such as Marriott and Hyatt, Opal White Cast Acrylic Diffuser Sheet is used as a shading medium for hidden light strips. Its elegant milky white appearance and customized texture structure not only bring uniform soft light when the lights are on, but also maintain visual beauty after the lights are turned off. Because its material does not contain heavy metals and has excellent heat resistance, it is particularly suitable for commercial lighting environments that operate 24 hours a day, helping customers achieve energy-saving goals while ensuring lighting quality.
In high-end factory workshops, dust-free laboratories and other occasions with extremely high requirements for lighting quality, the diffuser is used to customize lampshades and reflective panels to meet the comprehensive needs of anti-glare, anti-ghosting and uniform lighting. Many cooperative brands PHILIPS Industrial Lighting Department and Honeywell Smart Workshop Lighting Project all use Opal White Cast Acrylic Diffuser Sheet to improve the overall system energy efficiency and safety level. In addition, its excellent mechanical strength ensures long-term stable operation in industrial environments such as impact and vibration.
