  • Smooth finish suitable for detailed graphics and fine lettering

Calendered Vinyl, on the other hand, is produced by pressing and rolling vinyl into sheets. It tends to be thicker and less flexible than cast vinyl, making it better suited for flat or gently curved surfaces. This type of vinyl is generally more affordable but has a shorter lifespan and is more prone to shrinkage over time.

Important characteristics of calendered vinyl are:

  • Thicker and less flexible, suitable for flat or slightly curved surfaces
  • More economical compared to cast vinyl
  • Typically lasts 3 to 5 years outdoors, depending on conditions
  • Can be more prone to shrinkage and edge lifting

Specialty Vinyl Options for Enhanced Performance

Beyond the basic types, there are specialty vinyl options designed to enhance the performance and aesthetics of car decals. These include:

  • Reflective Vinyl: Contains glass beads or prismatic elements that reflect light, increasing visibility at night, commonly used for safety decals or emergency vehicles.
  • Metallic Vinyl: Offers a shiny, metal-like finish that mimics chrome or other metals, popular for decorative decals and branding.
  • Textured Vinyl: Includes finishes such as carbon fiber, brushed metal, or matte, providing a unique tactile feel and appearance.
  • Removable Vinyl: Designed for temporary applications, this vinyl can be removed without leaving residue, ideal for promotional or seasonal decals.

Each specialty vinyl type varies in durability and application ease, so it is essential to match the vinyl to the specific needs of the project.
