PVC, the full name is Polyvinylchloride, the main component is polyvinyl chloride, and other components are added to enhance its heat resistance, toughness, ductility, etc.
The top layer of PVC is lacquer, the main component in the middle is polyvinyl chloride, and the bottom layer is a back coating adhesive.
PVC material is a well-loved, popular, and widely used synthetic material in the world today. Its global usage is the second-highest among all 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, PVC production and consumption average 1.4 million tons. PVC is being produced and applied worldwide at a growth rate of 4%. The growth of PVC in Southeast Asia is particularly notable, 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 film and rigid PVC sheet. Among them, rigid PVC sheet accounts for about 2/3 of the market, and soft PVC accounts for 1/3. Soft PVC film is generally used for the surface of floors, ceilings, and leather. But because soft PVC contains softeners, it is easy to become brittle and difficult to store, so its scope of use is limited. This is also the difference between soft PVC film and rigid PVC sheet. Rigid PVC sheet does not contain softeners, so it has good flexibility, easy to form, not easy to be brittle, non-toxic and pollution-free, and has a long storage time. Due to its obvious advantages, it has great development and application value.
