The material is also called acrylic plastic, and sometimes loosely referred to as \u2018perspex\u2019.<\/p>\n<p>PMMA is characterized by properties such as high transparency and excellent UV resistance. It has a very high surface hardness and thus good scratch resistance.<\/p>\n<p>PMMA is often used as a replacement for glass due to its very high transparency and light transmission.<\/p>\n<p>Owing to its characteristic properties, PMMA is often used in outdoor applications such as lenses for vehicle taillights and various kinds of products used in the construction industry.
