When selecting transparent plastic materials for displays, signage, lighting, or indoor decor, acrylic (PMMA) sheet ve PS (polystyrene) sheet are two of the most common options. While they look similar at first glance, their optical clarity, mechanical strength, weather resistance, processability, and cost differ significantly. Choosing the right material directly affects product quality, service life, and budget.
In this article, we compare acrylic sheet and PS sheet side by side, so you can make the best choice for your project. At the end, we will also introduce how our company provides one-stop supply and custom fabrication services to meet your personalized needs.
What Is Acrylic (PMMA) Sheet?
Acrylic sheet (PMMA, Polymethyl Methacrylate) — also known as organic glass — is a high-performance transparent plastic. It offers crystal-clear transparency (92%+ light transmittance), high surface gloss, good toughness, and excellent UV resistance. It is widely used for high-end displays, outdoor signage, architectural glazing, safety barriers, and lighting covers.
Main Features of Acrylic Sheet
- Şeffaflık: 92–93% light transmittance, glass-like clarity, soft light transmission.
- Impact resistance: 10–16× stronger than glass, much tougher than PS, not easy to shatter.
- Hava koşullarına dayanıklılık: Excellent UV resistance, anti-yellowing, suitable for long-term outdoor use.
- Hardness & surface: Higher surface hardness, good scratch resistance (relative to PS).
- Temperature resistance: Stable at -40℃ to 100℃, suitable for various environments.
- Processing: Easy to cut, drill, polish, bend, glue, and print; supports high-precision customization.
What Is PS Sheet?
PS sheet (Polystyrene) — commonly called “organic board” — is an affordable, lightweight transparent plastic. It has good but slightly hazy transparency (88% light transmittance), low cost, and easy processability. It is mainly used for indoor frames, light boxes, low-cost displays, packaging, and stationery.
Main Features of PS Sheet
- Şeffaflık: ~88% light transmittance, slightly foggy, less bright than acrylic.
- Impact resistance: Brittle, easy to crack under impact; fragile compared to acrylic.
- Hava koşullarına dayanıklılık: Poor UV resistance; yellows and cracks quickly outdoors; for indoor use only.
- Hardness & surface: Lower surface hardness, easy to scratch; gloss decreases over time.
- Temperature resistance: Deforms easily above 60–70℃; not suitable for high-temperature environments.
- Processing: Low cost, easy to cut and print; not ideal for deep bending or polishing.
Acrylic Sheet vs PS Sheet: Comparison Table
| Karşılaştırma Öğesi | Acrylic (PMMA) Sheet | PS (Polystyrene) Sheet |
| Light Transmittance | 92–93% (crystal clear) | ~88% (slightly hazy) |
| Darbe Dayanımı | High, tough, not easy to shatter | Low, brittle, easy to crack |
| Weatherability (UV) | Excellent, anti-yellowing, outdoor-safe | Poor, yellows/cracks outdoors |
| Surface Hardness | Higher, better scratch resistance | Lower, easy to scratch |
| Isı Direnci | -40℃ to 100℃, stable | Deforms above 60–70℃ |
| İşlenebilirlik | Polishing, bending, gluing, high precision | Simple cutting/printing, limited bending |
| Typical Applications | Outdoor signage, displays, lighting, safety guards | Indoor frames, light boxes, low-cost displays |
| Price | Medium–high | Low, budget-friendly |
How to Choose: Acrylic or PS?
Choose Acrylic Sheet If You Need:
- High clarity & premium appearance (luxury displays, cosmetic counters, museum cases)
- Outdoor durability (outdoor signs, billboards, building glazing)
- Safety & impact resistance (protective barriers, machine guards, children’s products)
- Long service life (5–10 years without obvious yellowing)
- High-end finishing (polished edges, seamless bonding, precise thermoforming)
Choose PS Sheet If You Need:
- Low cost & mass production (cheap frames, indoor light boxes, simple displays)
- Indoor, short-term use (promotional stands, packaging, stationery)
- Basic printing & simple shapes (screen printing, flat cutting, no complex bending)
