PVC the top layer of the surface film is lacquer, the main component in the middle is polyvinyl chloride, and the bottom layer is back coating adhesive. It is a very popular, popular and widely used synthetic material in the world today. Its global usage ranks second in various synthetic materials. According to statistics, only in 1995 a year, not PVC production in Europe, there are about five million tons, and its consumption is five million and three hundred thousand tons. In Germany, the production and consumption of PVC averaged one million and four hundred thousand tons. PVC is being produced and applied worldwide with a growth rate of 4%. In recent years, the number of PVC growth in Southeast Asia is particularly significant, thanks to the urgent needs of infrastructure construction in Southeast Asian countries. PVC is the most suitable material for the production of three-dimensional surface masks.
PVC is a PVC, bright color, corrosion resistant, durable, due to an increase in the manufacturing process of plasticizer, anti ageing agent assisted a number of toxic materials, so their products generally do not store food and drug.
PVC can be divided into soft PVC and hard PVC. Among them, hard PVC accounts for about 2/3 of the market, soft PVC accounted for 1/3. Soft PVC is generally used in the floor, ceiling and leather surface, but because soft PVC contains softener (which is also the difference between soft PVC and hard PVC), it is easy to be crisp and difficult to save, so its use scope is limited. Hard PVC does not contain softener, so it has good flexibility, easy molding, easy to crisp, non-toxic, pollution-free, long storage time, so it has great development and application value. Hereinafter referred to as "PVC". The essence of PVC is a kind of vacuum plastic film. It is used in the surface packing of various kinds of panels, so it is also called decorative film and adhesive film. It is used in many fields, such as building materials, packaging, medicine and so on. Among them, the building materials industry accounted for the largest proportion, 60%, followed by the packaging industry, there are other small range of applications industry.
