PMMA – Polymethyl methacrylate
PMMA Elit
PMMA Elit was specifically developed for use in LED display boards. The material is a cast acrylic with excellent light-diffusion properties. It diffuses light evenly, and the light source is not detectable as a brighter spot. The material is suitable for use in interior design solutions, on public premises, and particularly in advertising displays. We deliver PPMA Elit as plastic sheets.
