We have really talked a lot about the relevant knowledge of PVC celuka board. In order to deepen everyone's knowledge and understanding of PVC sheet, then we will tell you about the perfect structure and application value of PVC sheet. Elaboration:
PVC sheet: 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 volume of PVC sheets in Europe was about 5 million tons, while its consumption was 5.3 million tons. In Germany, the production and consumption of PVC sheets averaged 1.4 million tons. PVC is being produced and applied worldwide at a growth rate of 4%. In recent years, the growth of PVC sheets 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 sheet can be divided into soft PVC and hard PVC. 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 is flexible, easy to form, not brittle, non-toxic and pollution-free, and has a long storage time, so it has great development and application value.
