The polymer microparticles "Tech Polymer," sold by Sekisui Chemical Co., Ltd., are used as light diffusion materials for display and lighting cover materials. Utilizing the characteristics of being spherical and transparent polymer microparticles, they provide a uniform light diffusion effect that brightens the entire display, and in lighting applications, they help to minimize the visibility of LED direct light (hotspot), reduce brightness unevenness, and enhance the overall brightness of the lighting cover. This time, we will freely publish the physical property data of plates made by adding Tech Polymer to resins (PC, PMMA) used in lighting applications.
