PMMA
PMMA: An Introduction
One of the most widely used plastics in the world, PMMA exhibits good chemical stability, mechanical properties, and weather resistance. The material is also simple to process and dye.
The transparent nature of PMMA makes it popular in the interior design, construction, and chemical industries, as well as in advertising for signs, lightboxes, and billboards.
