PETG vs Acrylic vs Polycarbonate — Which Clear Sheet Material Wins?
Introduction
Choosing the right transparent plastic sheet can make or break your project. Among the most common options are PETG, acrylic, and polycarbonate sheets. Here’s a clear comparison to help you make the best choice.
📊 1. Optical Clarity
-
PETG: Excellent clarity, often exceeding 90% light transmission.
-
Acrylic (PMMA): Very clear but more brittle.
-
Polycarbonate (PC): Clear but can show slight tint and scratches more easily.
💥 2. Impact Resistance
-
PETG: High impact resistance — significantly tougher than acrylic.
-
Acrylic: Prone to cracking under stress.
-
Polycarbonate: Extremely high impact strength — best for safety barriers.
🔧 3. Ease of Fabrication
-
PETG: Thermoforms and machines with minimal risk of cracking.
-
Acrylic: Machinable but more stress fractures possible.
-
Polycarbonate: Harder to work with and requires more careful tooling
