If you’re considering a vinyl wrap for your vehicle, signs, or decals, you may have come across the terms “calendared” and “cast” vinyl. Both types have their unique characteristics and ideal applications, so choosing the right one depends on your project’s needs. Let’s dive into the differences!
Calendared Vinyl: Rolled and Stretched Like Pizza Dough
Picture a pile of pizza dough being rolled and stretched out—that’s similar to the process used to create calendared vinyl. This vinyl starts as a solid, thick material that’s gradually rolled and pressed out into a thin film. Because it’s stretched during production, calendared vinyl is a bit thicker and less flexible compared to cast vinyl.
Pros of Calendared Vinyl:
- Cost-effective: The manufacturing process is simpler and more affordable, making it ideal for budget-conscious projects.
- Durability: While it may not last as long as cast vinyl, it’s still durable, particularly in indoor or short-term outdoor settings.
Cons of Calendared Vinyl:
- Less flexibility: Since it’s rolled out, it tends to be stiffer and has a tendency to shrink slightly over time, making it best suited for flat or gently curved surfaces.
- Limited longevity: Calendared vinyl generally lasts between 3 to 5 years outdoors, as it can become brittle and less adhesive over time. (This is also dependent on where you are based in the climatic zone.)
Best Uses for Calendared Vinyl: Calendared vinyl is often used for shorter-term or indoor applications depending on whether it is a monomeric vinyl or a polymeric vinyl. Examples of applications are:
- Vehicle graphics on flat surfaces
- Wall decals and other indoor projects
Cast Vinyl: Poured and Set Like a Perfect Pancake
Now, imagine pouring a smooth pancake batter onto a griddle and letting it cook into shape. Cast vinyl is made by pouring a liquid mixture onto a casting sheet, where it’s allowed to settle and “cure” naturally. This process doesn’t stretch the material, so cast vinyl emerges as a thinner, highly flexible film.
Pros of Cast Vinyl:
- Superior flexibility: Cast vinyl easily conforms to curves, rivets, and complex surfaces, making it ideal for vehicle wraps.
- Long-lasting durability: Since there’s no stress on the material during manufacturing, it holds up better under sunlight, extreme temperatures, and weather, with a lifespan of up to 10 years. (This is again also dependent on where you are based in the climatic zone.)
Cons of Cast Vinyl:
- Higher cost: The manufacturing process is more involved, which makes cast vinyl more expensive. However, this cost often pays off in longevity and performance.
Best Uses for Cast Vinyl: Cast vinyl is typically used for premium, long-term applications, such as:
- Full vehicle wraps and decals on curved or contoured surfaces
- Outdoor signs with exposure to the elements
- Or any project requiring a professional, long-lasting finish
Which One Should You Choose?
If your project requires flexibility, durability, and a flawless finish for years, cast vinyl is the best investment. However, for flat surfaces or short-term projects where cost is a primary factor, calendared vinyl offers great performance without breaking the bank.
In Summary:
- Calendared Vinyl: Rolled out like pizza dough; thicker, stiffer, cost-effective, best for flat or gently curved surfaces.
- Cast Vinyl: Poured like pancake batter; thin, flexible, long-lasting, best for complex shapes and high-end applications.
Choosing between calendared and cast vinyl doesn’t have to be overwhelming. Think about your project’s demands, the surface type, and your budget, and you’ll find the perfect vinyl match!
