What is the material of the car sticker?

Since the body stickers need to be used outdoors and require sun protection and rain protection, the materials usually used are PVC or PET.

The material of car stickers is mainly PVC outdoor special adhesive stickers that can adapt to outdoor conditions. Although the materials and colors are not as rich as clothing fabrics, there are also many options such as fluorescence, matte, metal reflection, laser reflection, and metal drawing. Car stickers are omnipresent in the whole car. On both sides of the body, on the hood, light eyebrows, skirts, and wheels, as long as reasonable creations are made within the scope permitted by the current regulations, the owner's personality and hobbies can be fully demonstrated. Car stickers are not the patent of young people. People of all ages, as long as they love car culture and life, can find fun in car stickers.

PVC products are chemically resistant and have strong resistance to oxidants, reducing agents and strong acids. However, it can be corroded by concentrated oxidizing acids such as concentrated sulfuric acid and concentrated nitric acid, and is not suitable for contact with aromatic hydrocarbons and chlorinated hydrocarbons.

PVC has the advantages of flame resistance, self-extinguishing, abrasion resistance, noise reduction, high strength, good electrical insulation, low price, wide material sources, and good airtight performance.

The disadvantage of PVC is that it has poor thermal stability and is prone to aging under the effects of light, heat and oxygen. The long-term use temperature of most polyvinyl chloride plastic products should not exceed 55°C, but the long-term use temperature of specially formulated PVC plastics can reach 90°C.

PVC has non-flammability, high strength, weather resistance and excellent geometric stability, and has strong resistance to oxidants, reducing agents and strong acids. In addition, because of its good flexibility, shrinkage and opacity, good processing and labeling performance, strong chemical resistance, strong and durable, it is suitable for long-term outdoor use.

PET polyester film is made of polyethylene terephthalate. PET has excellent physical and mechanical properties in a wide temperature range, and the long-term use temperature can reach 120°C. Excellent electrical insulation, even at high temperature and high frequency, its electrical performance is still good. But the corona resistance is poor, non-toxic, weather resistance, chemical resistance, creep resistance, fatigue resistance, friction resistance, and dimensional stability are good. Low water absorption, resistant to weak acids and organic solvents, but not immersed in hot water or alkali.

Since the knife-engraved sticker can ensure that the logo of the racing sponsor is clear and high-quality on the car, and the high-grade sticker will not damage the paint and gloss of the racing car after being removed. Therefore, the current international racing car generally adopts a knife-cut sticker manufacturing process, and the self-adhesive material is the best American brand 3M. With the advancement of technology, 3M invented reflective stickers in the 1990s and was gradually used to make car stickers. The eye-catching colors and night reflections not only dazzled, but greatly improved the safety of cars. Taking this as a journey, car stickers gradually have the four characteristics of numbering, branding, decoration and safety.
