PMMA / Acrylic LED Diffusers
Acrylic for clarity, surface hardness and long-term colour stability.
Material
Why PMMA
PMMA, commonly called acrylic, is chosen where clarity, surface hardness and long-term colour stability come first. It resists yellowing well, which is why it is the standard for architectural interiors and outdoor signage, and it takes a hard, scratch-resistant finish. Its impact strength is lower than polycarbonate.
Comparison
PMMA vs polycarbonate
| Polycarbonate (PC) | PMMA / acrylic | |
|---|---|---|
| Optical characteristics | Very good transmission, slightly higher haze | Excellent clarity, low haze |
| Impact resistance | Very high | Moderate |
| Surface finish | Good; softer surface needs careful handling | Hard, scratch-resistant surface |
| Appearance | Slightly warm tint | Water-clear |
| Typical applications | Industrial, outdoor, vandal-resistant | Architectural, commercial, signage |
| Customization | Profile, colour, surface, two-colour | Profile, colour, surface, two-colour |

FAQ
Frequently Asked Questions
Is PMMA the same as acrylic?
Yes. PMMA is polymethyl methacrylate; acrylic is the common trade name.
Does acrylic yellow over time?
PMMA has very good UV stability and low yellowing compared with many transparent polymers.
