What is PMMA better known as?

PMMA, or polymethyl methacrylate, is more commonly recognized as acrylic. This material is known for its clarity, making it a popular choice for applications requiring transparency, such as in display cases, lenses, and signs. Acrylic is versatile, lightweight, and can be easily molded, which adds to its wide range of uses in design and manufacturing.

When it comes to the alternatives, high density polyethylene is a different type of plastic that is known for its strength and durability, primarily used in containers, pipes, and plastic bags. Polypropylene is another distinct polymer recognized for its resistance to chemical and thermal damage, often used in packaging and automotive components. Elastomers, on the other hand, are materials characterized by their elasticity, which is entirely different from the rigid structure of PMMA. This distinction highlights why PMMA is specifically referred to as acrylic, given its unique properties and applications.
