What Material is Used for Car Decals?
1 Answers
Car decals primarily use PVC outdoor-specific adhesive paper that can withstand outdoor conditions. Here are the detailed specifications: 1. Material Description: The decals employ pressure-sensitive technology with cast-grade and calendered-grade films. Cast-grade film contains a blended solution of PVC plasticizers, macromolecular plasticizers, pigments, anti-aging agents, solvents, and additives. Calendered-grade film consists of molten materials including PVC plasticizers, small-to-macromolecular plasticizers, pigments (a key factor determining various physical properties of PVC film), anti-aging agents, and additives. 2. Structure of Car Decals: The first layer is the film/decal layer, the second is the adhesive backing layer, and the third is the release liner. With increasingly refined adhesive backing technology, the advantage of repositionable car decals lies in allowing pre-printed designs to be temporarily positioned on the vehicle body. Once the optimal placement is found, using a squeegee to press the adhesive ensures firm adhesion, achieving seamless integration with the vehicle surface.
