Acrylic vs. Polystyrene: What's the Difference?

Edited by Sawaira Riaz || By Sumera Saeed || Updated on November 2, 2023
Acrylic is a transparent plastic material with outstanding strength and optical clarity, while polystyrene is a lightweight, typically non-transparent thermoplastic used in a variety of applications.

Key Differences
Acrylic, known as polymethyl methacrylate (PMMA), offers excellent optical clarity and is often used as a glass alternative. Polystyrene, a petroleum-based plastic, is less clear and often used in the production of disposable consumer goods.
