PVC, the full name of which is polyvinyl chloride, is mainly composed of polyvinyl chloride, and other components are added to enhance its heat resistance, toughness and ductility. The top layer of this surface film is paint, the main component in the middle is PVC, and the bottom layer is adhesive. It is a kind of synthetic material which is deeply loved, quite popular and widely used in the world today. Its global usage ranks second among all kinds of synthetic materials. According to statistics, only in 1995, the production of PVC in Europe was about 5 million tons, while its consumption was 5.3 million tons. In Germany, the average output and consumption of PVC is1400,000 tons. The production and application of PVC in the world is growing at a rate of 4%. In recent years, the growth of PVC in Southeast Asia is particularly remarkable, which is attributed to the urgent demand for infrastructure construction in Southeast Asian countries. Among the materials that can be used to make three-dimensional surface films, PVC is the most suitable material. PC is the abbreviation of polycarbonate, and the English word for polycarbonate is PC engineering plastic. PC material is actually a kind of engineering plastics. As a widely used material in the world, PC has its own characteristics, advantages and disadvantages. PC is an amorphous thermoplastic resin with excellent comprehensive properties, which has excellent electrical insulation, ductility, dimensional stability, chemical corrosion resistance, high strength, heat resistance and cold resistance. It also has the advantages of self-extinguishing, flame retardant, non-toxic and colorable. You can see the shadow of PC plastic in every corner of your life, and the characteristics of large-scale industrial production and easy processing also make it extremely cheap. Its strength can meet all kinds of requirements from mobile phones to bulletproof glass. The disadvantage is that it is not hard enough compared with metal, and its appearance is easy to scratch, but its strength and toughness are good. Whether it is heavy pressure or general knocking, as long as you don't try to hit it with a stone, the time is long enough.
