Temperature Change Vinyl is a unique thermochromic film that reacts to temperature shifts—changing color when exposed to heat or cold. Designed to cut, weed, and apply just like standard vinyl, this specialty film adds a dynamic, color-changing effect to custom projects, especially drinkware and glassware. Choose from four cold-activated films—Cold Blue, Cold Pink, Cold Purple, and Cold Pink Purple—which transform when chilled below 59ºF. Cold Blue, Cold Pink, and Cold Purple begin as a frosted translucent shade, while Cold Pink Purple starts pink and changes to purple. For heat-activated applications, Red Hot Yellow transitions from red to yellow above 104ºF (40ºC) and returns to red when cooled. Each film is backed with a permanent acrylic adhesive for reliable sticking power on smooth, clean surfaces. Key Features: Color changes with heat or cold exposure Cuts, weeds, and transfers easily Frosted finish on select cold colors Permanent adhesive for lasting results Ideal for drinkware, tumblers, and glass projects Applications: Custom cups, mugs, glassware, seasonal decals, novelty items
