PrintLink's Recommendation
Which material should you choose?
PrintLink generally recommends acrylic for polished lobby signs, dimensional lettering, plaques, and premium displays. Choose polycarbonate for protective glazing, impact-prone locations, formed faces, and applications where breakage resistance is more important than scratch resistance.
Quick comparison
| Feature | Acrylic | Polycarbonate |
|---|---|---|
| Clarity | Excellent, glass-like appearance | Very clear, slightly less glass-like |
| Impact resistance | Stronger than glass but can crack | Exceptionally impact resistant |
| Scratch resistance | Better surface hardness | Scratches more easily |
| Fabrication | Cuts, polishes, and engraves beautifully | Tough and formable, requires proper technique |
| Cost | Often lower for sign-grade sheets | Often higher |
| Best fit | Premium displays and decorative signage | Protective and impact-resistant applications |
Best uses for each material
Acrylic is best for
- Lobby signs
- Dimensional letters
- Plaques and directories
- Back-printed displays
- Polished decorative panels
Polycarbonate is best for
- Protective covers
- Vandal-prone locations
- Machine guards
- Formed sign faces
- Impact-resistant glazing
Strength and breakage
Polycarbonate is the clear choice when impact is the main concern. Acrylic is much more impact resistant than ordinary glass but can crack or chip under a severe blow. Polycarbonate bends and deforms before it breaks in many situations.
Clarity and appearance
Acrylic has outstanding optical clarity and can be flame-polished or mechanically polished for a glass-like edge. Polycarbonate is also transparent, but it is selected more often for performance than for a luxury polished appearance.
Scratching and maintenance
Acrylic has a harder surface and generally resists everyday scratching better. Polycarbonate scratches more readily, although hard-coated grades are available. Both should be cleaned with compatible non-abrasive products.
Fabrication and forming
Acrylic cuts, engraves, bonds, and polishes well, making it excellent for display fabrication. Polycarbonate is tougher and better for cold bending or impact-resistant formed parts, but heat, tools, and cleaning chemicals must be selected carefully.
Which should you choose?
Choose acrylic when visual quality and polished presentation matter most. Choose polycarbonate when the panel may be struck, vandalized, flexed, or used as a protective barrier.
Pros and cons
Acrylic
Advantages
- Excellent optical clarity
- Polished premium appearance
- Better scratch resistance

Limitations
- Can crack from hard impact
- Edges may chip during poor fabrication
- Not ideal for severe vandalism
Polycarbonate
Advantages

- Better choice in breakage-sensitive locations
Limitations
- Scratches more easily
- Usually costs more
- Certain cleaners and coatings can cause damage
Frequently asked questions
Which is stronger, acrylic or polycarbonate?
Polycarbonate is significantly more impact resistant. Acrylic is rigid and durable but is more likely to crack under a hard strike.
Which one looks more like glass?
Acrylic usually provides the most glass-like clarity and polished edge appearance.
Can acrylic be used outdoors?
Yes. Sign-grade acrylic is commonly used outdoors, but thickness, color, expansion, mounting, and UV exposure should be considered.
Does polycarbonate turn yellow?
UV-resistant and coated polycarbonate products are designed to improve weathering, but the exact product grade matters. Always choose a sheet intended for the exposure.
Which is better for a lobby sign?
Acrylic is usually preferred because of its optical clarity, polished edges, color options, and premium finished appearance.
Still deciding?
Tell PrintLink where the sign will be used, how large it needs to be, and how long you expect it to last. We’ll recommend the right material for the job.
