PMMA, also known as acrylic, is a transparent thermoplastic. One of the most widely used plastics in the world, PMMA demonstrates good chemical stability, mechanical properties and weather resistance. The material is also easy to process and to dye.

Because of its transparency, PMMA is often used as an alternative to glass and is popular in the interior design, construction and chemical industries. It is also regularly used in advertising to fabricate signage, lightboxes and billboards.
