PC Sheet vs Acrylic Sheet: Complete Comparison Guide
What's the Difference Between PC Sheet and Acrylic Sheet?
PC sheet (Polycarbonate) and acrylic sheet (PMMA, Polymethyl methacrylate) are the two most common engineering plastic sheets. When purchasing, many buyers and engineers struggle with the question "which material is better." In reality, the answer depends on your specific application — there is no absolute better or worse, only suitable or not.
Core Parameter Comparison Table
| Dimension | PC Sheet (Polycarbonate) | Acrylic Sheet (PMMA) | Recommendation |
|---|---|---|---|
| Light Transmittance | 85–90% | ≥92%, higher clarity | Display/optical → Acrylic |
| Impact Strength | 250× glass, excellent | 10× glass, moderate | Protection/outdoor → PC |
| Temperature Range | -40°C to +130°C | -30°C to +80°C | High-temp → PC |
| Flame Retardancy | Optional UL94 V-0 | UL94 HB (flammable) | Fire-rated → PC |
| Processability | Higher (prone to stress cracking) | Easy (laser/CNC both great) | Complex shapes → Acrylic |
| Surface Hardness | Medium (hard-coat available) | Higher (good surface hardness) | Abrasion → Acrylic |
| Chemical Resistance | Poor (esters/ketones) | Moderate | Chemical contact → Avoid PC |
| Price Level | Medium-high | Lower | Budget → Acrylic |
| Outdoor Lifespan | 10–15 yrs (UV-stabilized) | 5–8 yrs (yellowing) | Long-term outdoor → PC |
Selection Flowchart (Text Version)
Follow this decision tree to quickly find the right material for you:
- Do you need high light transmittance (>90%)?
Yes → Acrylic sheet ✅
No → Go to step 2 - Do you need impact resistance / outdoor use?
Yes → PC sheet (recommend UV coating) ✅
No → Go to step 3 - Do you need high temperature resistance (>80°C)?
Yes → PC sheet ✅
No → Go to step 4 - Is budget limited?
Yes → Acrylic sheet ✅
No → Choose based on precision needs
Best Applications for PC Sheet
- Machine guards: Impact-resistant, prevents splashing, protects operators
- Outdoor signage / light boxes: UV-resistant, anti-aging, long lifespan
- Greenhouses / sunrooms: High light transmission + impact resistance, safe
- Electronics enclosures: Insulating, flame-retardant, heat-resistant
- Drone components: Lightweight + high strength
Best Applications for Acrylic Sheet
- Jewelry / cosmetics displays: High clarity + gloss, premium look
- Supermarket / convenience store displays: Flexible processing, versatile shapes, low cost
- Museum / gallery display cases: High transparency, doesn't obstruct viewing
- Advertising signage / light box panels: Great for screen printing / UV printing, vivid colors
- Furniture / interior decoration: Free-form shapes, decorative lighting effects
Combining Both: Chaorong's Integrated Solution
Some applications need both PC sheet and acrylic sheet, for example:
- Protection + display combo cover: Outer PC (protection) + inner acrylic (display)
- Double-layer partition: PC load-bearing layer + acrylic display layer
Chaorong Electronics supplies both PC and acrylic sheets, supports custom processing from your drawings, and can help design the optimal material combination — one order solves both needs.
Frequently Asked Questions
Q1: Which is more expensive, PC sheet or acrylic sheet?
Generally, PC sheet is 20–40% more expensive than acrylic, but PC offers better impact and weather resistance, so its long-term cost is actually lower.
Q2: Can PC sheet be laser cut like acrylic?
Yes, but PC laser cutting requires fume control and thermal-stress management. We recommend a CO₂ laser cutter operated by a professional manufacturer.
Q3: Which to choose for outdoor use?
For outdoor use, PC sheet with UV coating is strongly recommended; acrylic tends to yellow and become brittle outdoors.
Q4: Can I buy both PC and acrylic sheets at once?
Yes. Chaorong Electronics supplies both materials, supports custom processing from your drawings, and solves your needs in one stop.
