1. Lightweight: Acrylic has a density of 1.19, which is only half of glass. When making large external advertising light boxes, it is easy to install, safe, and has high impact resistance. 2. Good weather resistance: It has good outdoor high-temperature weather resistance function and is not prone to "brittleness" phenomenon during long-term outdoor use. 3. Easy to form: Acrylic can be processed according to customer needs through cutting, drilling, trimming, polishing, screen printing, laser, engraving, painting, vacuum forming, bending, hot stamping, bonding and other processing techniques. It can produce various ideal shapes with extremely rich expressive power and a tensile strength of up to 70Mpa. 4. Good light transmission: The initial light transmission rate reaches 93%, and the processed acrylic on the surface is crystal clear and bright in color.

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:
