1. The mechanical and thermal properties of acrylic itself do not change, making it easy to process and shape. It can be used for lenses, display screens, or popular curved screens; 2. While preventing blue light, it also prevents ultraviolet light. As shown in the spectral test chart below, the light transmittance in the wavelength band below 450nm is close to zero, indicating that the blocking rate between the ultraviolet and strong blue light bands is very high; 3. The product has a soft color and is not dazzling when used on screen materials or screen protectors of electronic devices; 4. The thickness can be customized according to the needs, and it is also applicable to products such as glasses that require lenses of different thicknesses.

Acrylic is a plastic polymer material. When selecting materials, it is necessary to choose acrylic sheets that are brand new and have relevant performance parameters that meet the requirements of the national standard GB/T 7134-2008. Otherwise, some performance and weather resistance cannot be guaranteed. Under normal usage conditions, the fading is not significant within three years (except for specially designated indoor color boards). The performance parameters of the new acrylic material are shown in the following table:
