So what exactly is PVC? PVC, the full name is Polyvinylchlorid, the main component is polyvinyl chloride, and other components are added to enhance its heat resistance, toughness, ductility, etc. The top layer of this surface film is lacquer, the main component in the middle is polyvinyl chloride, and the bottom layer is back-coated adhesive. It is a kind of synthetic material that is well-loved, popular and widely used in the world today. Its global usage ranks second among various synthetic materials. According to statistics, in 1995 alone, the production of PVC in Europe was about 5 million tons, while its consumption was 5.3 million tons. In Germany, the production and consumption of PVC averaged 1.4 million tons. PVC is being produced and used worldwide at a growth rate of 4%. The growth of PVC in Southeast Asia has been particularly remarkable, thanks to the urgent need for infrastructure construction in Southeast Asian countries. Among the materials that can produce three-dimensional surface films, PVC is the most suitable material.
PVC can be divided into soft PVC and hard PVC. Among them, hard PVC accounts for about 2/3 of the market, and soft PVC accounts for 1/3. Soft PVC is generally used for floors, ceilings and leather surfaces, but because soft PVC contains softeners (this is also the difference between soft PVC and hard PVC), it is easy to become brittle and difficult to store, so its scope of use is limited. Hard PVC does not contain softener, so it has good flexibility, easy to shape, not easy to be brittle, non-toxic, non-polluting, long storage time, so it has great development and application value. Below are referred to as PVC. The essence of PVC is a kind of vacuum blister film, which is used for the surface packaging of various panels, so it is also called decorative film, adhesive film, and is used in many industries such as building materials, packaging, and medicine. Among them, the building materials industry accounts for the largest proportion at 60%, followed by the packaging industry, and there are several other small-scale applications.
