Introduction of PMMA

Polymethyl methacrylate, commonly known as PMMA, is a transparent and versatile synthetic polymer with a wide range of applications. It is a type of acrylic material that offers optical clarity, high impact resistance, and ease of processing, making it a popular choice in various industries. PMMA is recognized for its ability to mimic the appearance of glass while being lighter and more shatter-resistant, which has led to its use in both practical and aesthetic applications.
