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:
