Acrylic vs. Polycarbonate: The Power Duo of Signage
Acrylic – The Glossy Pro
Acrylic, often branded as Plexiglas, is your go-to for a crystal-clear, high-gloss finish. It’s lightweight, durable, and gives off that high-end vibe, making it a popular choice for illuminated signs and lobby displays.
- Thickness Options: Commonly available in 1/16” to 1” thicknesses, with 1/8”, 3/16″ and 1/4” being signage favorites.
- Standard Sizes: 4×8 feet, with some suppliers offering custom cuts up to 5×12 feet or more.
Characteristics:
- Crystal Clarity: Acrylic is known for its glass-like transparency and polished look.
- Weather-Resistant: Holds up well under sunlight without yellowing.
- Best Uses: Indoor signs, backlit signs, and anything that needs a classy, high-gloss finish.
Polycarbonate – The Tough Guy
Polycarbonate (aka Lexan) is like acrylic’s tougher, impact-resistant cousin. It’s durable and less prone to breaking, making it perfect for high-traffic areas.
- Thickness Options: Similar to acrylic, with 1/8”, 3/16″ and 1/4” being the most common.
- Standard Sizes: 4×8 feet, with larger sheets like 6×12 feet, and rolls available for big projects.
Characteristics:
- Impact Resistance: It’s 250 times stronger than glass, perfect for high-impact areas.
- Temperature-Resistant: Won’t become brittle in extreme cold.
- Yellowing Over Time: Polycarbonate can yellow after prolonged UV exposure.
- Best Uses: Outdoor signage, protective shields, and any place you’d expect heavy wear and tear.
Quick Tip: Want to shine indoors? Go with acrylic. Need durability outdoors? Polycarbonate has your back.

Vinyl Film: Flexible, Vibrant, and Versatile
Vinyl film is an industry staple, used to cover signs, glass, walls, and vehicles. With a range of colors, finishes, and specialty options, vinyl offers nearly limitless design possibilities.
Types of Vinyl Film
- Frosted: Great for privacy screens and decorative accents on glass.
- Reflective: Perfect for nighttime visibility, like safety signs.
- Metallic and Chrome: Adds a high-end, reflective finish to your design.

Best Uses:
- Vehicle Wraps: Cast vinyl shines here.
- Glass and Window Graphics: Frosted or etched vinyl for privacy and style.

Pro Tip: Make sure the surface is clean and dust-free before application for a seamless finish.
Metal-Laminated Materials: Chemetal and Wilsonart for That Premium Look
When you want a luxurious, metallic finish without the weight of solid metal, metal-laminated materials like Chemetal and Wilsonart are your best bets. These materials offer real metal finishes on a lightweight substrate, adding high-end appeal to any signage project.

Final Thoughts: Choosing the Right Material Matters
The right material choice for a sign impacts everything from appearance and durability to readability and cost. Acrylic, polycarbonate, ACM, vinyl, and metal laminates each offer unique advantages, making it essential to consider your project’s specific requirements.
