Choosing the correct substrate (material) for wall signs is important because it will determine the sign's overall look, feel, and durability. Let's take a closer look at each substrate option. PVC PVC, or polyvinyl chloride, is a popular choice for wall signs. PVC is made by combining vinyl chloride monomers with additives. These additives include stabilizers, plasticizers, and lubricants. PVC comes in a variety of thicknesses and is primarily used indoors. These signs include vinyl banners, window decals, and yard signs. However, PVC has a few drawbacks. First, it is not as environmentally friendly as other substrates. Second, PVC is not UV-resistant and can turn yellow over time. Third, PVC is not as strong as other substrates which is not ideal for large or heavy signs. Acrylic Acrylic, also known as polymethyl methacrylate (PMMA), is a transparent plastic often used in place of glass. Acrylic is made by combining methyl methacrylate monomers. Acrylic is a popular choice for wall signs because it is shatter-resistant, lightweight, and easy to work with. Acrylic signs can be used indoors and outdoors. Of all the possible manufacturing materials, acrylic is one of the few which are naturally UV-resistant. With only a 3% degradation rate over ten years when used outdoors, it is not surprising this transparent plastic is becoming increasingly popular among manufacturers. Additionally, acrylic has good scratch resistance, making it an ideal material for products meant to last a long time. Aluminum Aluminum is a durable metal often used for wall signs. Aluminum is made by combining aluminum atoms into a lattice structure. This is turned into sheets which are used for signs. Some of these signs include building signs, directional signs, and ADA signs. Aluminum is a popular choice for wall signs because it is durable and weather resistant. Aluminum signs can be used indoors and outdoors. Aluminum also has a few drawbacks. First, it is more expensive than other substrates. Second, aluminum is not as easy to work with as most substrates. Third, aluminum can be susceptible to denting and scratching. Dibond Dibond is a composite material made by combining two pieces of aluminum around a polyethylene core. Dibond is often used for wall signs because it is strong, durable, and weather-resistant. These signs include building signs, trade show displays, and POP displays. Dibond has a few advantages over other substrates. First, it is lightweight and strong. Second, it is easy to work with. Third, it is weather-resistant. However, it has its drawbacks as well. First, it is more expensive than other substrates. Second, it is not as easy to cut. Third, Dibond can be difficult to print on.
