Overview
Poly(Methyl Methacrylate) (PMMA), also known as acrylic or plexiglass, is a transparent thermoplastic polymer obtained by polymerizing Methyl Methacrylate (MMA).
- Up to 92% light transmission – comparable to glass.
- Lightweight & durable – impact resistant and scratch resistant.
- Weather-resistant – UV and outdoor stability.
- Dimensional stability – retains shape under stress and heat.
Its unique combination of optical clarity, strength, and reliability makes PMMA a superior alternative to glass in industrial and commercial applications.

Frequently Asked Questions
Is polymethyl methacrylate PMMA or acrylic?
Yes, PMMA is commonly known as acrylic or plexiglass.
What is the difference between PMMA and MMA?
- MMA: Methyl Methacrylate, the liquid monomer.
- PMMA: Poly Methyl Methacrylate, the solid polymer.
Is PMMA safer than MMA?
Yes. PMMA is a stable, non-toxic polymer, while MMA is volatile and hazardous in liquid form.
Is acrylic (PMMA) recyclable?
Yes, PMMA is recyclable and can be converted back into MMA for reuse.
