Exterior Sign Materials 101: The Pros and Cons of Acrylic and Polycarbonate

When it comes to selecting the best option for exterior signs, Acrylic and Polycarbonate are two of the most popular materials in the sign industry, they both have their own unique properties that make them suitable for different types of applications.

Acrylic, also known as polymethyl methacrylate (PMMA), is a thermoplastic material that is commonly used in the sign industry for its durability and resistance to impact. This makes it an ideal choice for signs that will be exposed to the elements or installed in high-traffic areas. Acrylic is also UV resistant which means it will not yellow or degrade over time when exposed to sunlight, making it a great option for signs that will be installed in areas with high UV exposure, such as near the coast or outdoor. Acrylic is also easy to work with, it can be easily cut, shaped, and formed into a variety of different shapes and sizes, making it a popular choice for custom signs, it also offers a high level of transparency, which makes it a good choice for illuminated signs.

Another key benefit of acrylic is its versatility when it comes to design, it comes in a wide range of colors and it can be painted, printed or laser engraved which makes it easy to match the color of the sign to your brand or the surrounding environment. Furthermore, acrylic is a great option for signs that require a high level of detail and complexity, it can be molded into intricate shapes, making it a popular choice for 3D signs and sculptures, it can also be used to create illuminated signs with a unique and attractive design.

On the other hand, polycarbonate is a type of thermoplastic that is known for its high impact resistance, this makes it an excellent choice for exterior signs that will be installed in high-traffic areas or in areas prone to vandalism. This material can withstand heavy impacts, making it a perfect choice for signs that are likely to be hit by cars, bicycles or other objects. This high-impact resistance is due to its toughness and ability to flex under stress, making it less likely to crack or break.

Another benefit of polycarbonate is its UV resistance, this means it will not yellow or degrade over time when exposed to sunlight. This makes it an ideal option for outdoor signs, it is able to maintain its color and clarity even after long periods of exposure to the sun, which will keep your sign looking new for longer.

Polycarbonate is also flame resistant and it has a high level of transparency, which makes it a good option for illuminated signs as well. It is also an affordable option, it is generally cheaper than acrylic, which makes it a great choice for cost-conscious businesses, who still want a high-quality sign.

Polycarbonate is also a good option for signs that have a more simple or basic design. Its rigidity makes it easy to shape and mold into different forms and thicknesses and it can be easily cut and shaped to create signs with a clean, simple design. It is also suitable for double-sided signs, as it can be printed on both sides, creating a sign that can be seen from different angles.

When deciding between acrylic and polycarbonate for an exterior sign application, it is important to consider the specific requirements of the sign and the environment in which it will be installed. Factors such as the location, size, design, budget, and level of impact resistance or UV resistance are all important to consider.

Acrylic is a good choice for signs that require high transparency, UV resistance, and intricate designs, while polycarbonate is a good choice for signs that require high impact resistance, affordability and simple designs. Both materials offer their own unique benefits and drawbacks, but with a little research, you can choose the best option for your specific needs.

In conclusion, Acrylic and Polycarbonate are both excellent materials for exterior signs, and the choice between them will depend on the specific requirements of the sign, the location and the budget. Both materials are UV resistant and durable, but each has its own unique properties that make them suitable for different types of applications. A professional sign company can help you to navigate through the different options, to ensure that your sign is effective in promoting your brand and attracting customers.
