2.PVC material: PVC material is PVC, which is one of the largest plastic products in the world. It is cheap and widely used. PVC resin is white or light yellow powder, which cannot be used alone and must be modified.
PVC is a white powder with amorphous structure, with low branching degree and poor stability to light and heat. Different additives can be added according to different uses, and PVC plastics can show different physical and mechanical properties. Adding a proper amount of plasticizer into PVC resin can make various hard, soft and transparent products.

Functions of 3M film:
The main function of automobile body reflective stickers is to reflect light in the direction of light source projection by using the unique properties of reflective materials of reflective films. The purpose is that when the car is driving at night, drivers in all directions can notice the existence of the car for the first time.
Achieve the ultimate goal of improving the driving safety factor. There are many kinds of materials used in reflective stickers: PET, acrylic and so on. In layman's terms, plastic is waterproof.
The high-quality reflective film should have a reflective clarity of more than 6m at night, and the inferior film will have a foggy feeling. At present, the reflective brightness of 3M reflective film is 6 times that of traditional logo. During the day, the logo will appear bright white. At night, the sign provides a super reflective effect. It can also isolate ultraviolet rays. The ultraviolet isolation layer of the car film is a single-layer high-pressure coating.
