Many different materials are used to make custom signs, but one of the most popular and versatile materials is PVC (polyvinyl chloride). PVC is a thermoplastic polymer used in many industries, including custom sign fabrication.
Below we review the importance of PVC in custom sign making and which types of signs are made from PVC. It also explains how PVC is shaped to make signs and why it is such an important substrate in custom sign making.
What is a Substrate?
In sign making, a substrate is the base material on which a design is printed or carved. The most common substrates are PVC, aluminum, and acrylic. Each substrate has different benefits. The base substrate will be chosen based on the needs and budget for the sign project.
What is PVC, and How is it Made?
PVC, or polyvinyl chloride, is a type of plastic used in many products, from piping and tubing to window frames and toys. PVC is made by combining two simple ingredients: ethylene (a petroleum product) and chlorine (a common industrial chemical).
In its simplest form, PVC is a white powder mixed with other ingredients to make various products. Manufacturers add plasticizers to make soft PVC plastics like tubing and raincoats, which make the plastic more flexible.
Manufacturers add stabilizers to make harder plastics like pipes and siding, which help the plastic keep its shape. Adding fillers like glass fibers transform PVC into fiberglass-like sheets. No matter what form it takes, PVC is one of the world’s most versatile and widely used plastics.
Why is PVC Used in Custom Signs?
PVC is an ideal substrate for custom signs because it is strong, durable, and weather-resistant. It is used for indoor and outdoor signs and will not rust, fade, or crack easily. Additionally, PVC is lightweight and easy to work with, making it a good choice for both small and large signs.
How is PVC Shaped into Signs?
- Cut into any shape with various methods, including die-cutting, laser cutting, and waterjet cutting.
- Molded into shapes with thermoforming or injection molding.
- Extruded through a die into long pieces and cut to any desired length.
Common sign types made from PVC include:
- Banners
- Yard Signs
- Channel Letters
- Pylon Signs
- A-Frame Signs
- And many more…
