PMMA is an amorphous thermoplastic polymer with outstanding optical properties, making it an excellent choice for applications where high transparency and visual clarity are required. Often referred to as acrylic or acrylic glass, PMMA combines excellent weather resistance with high surface quality and long-term optical performance.

Considerations

PMMA offers excellent transparency and weather resistance but is less impact-resistant than polycarbonate (PC). Material selection should therefore take into account the mechanical and safety requirements of the application.
