PVC is being produced and applied worldwide at a rate of 4%. In recent years, the growth of PVC in Southeast Asia has been particularly significant, 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. Hard PVC accounts for about 2/3 of the market, and soft PVC accounts for 1/3. Soft PVC is generally used for the surface of floors, ceilings and leather, but because soft PVC contains softener (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 has been limited. Hard PVC does not contain softener, so it has good flexibility, easy to form, is not brittle, non-toxic and non-polluting, and has a long storage time, so it has great development and application value. The essence of PVC is a vacuum blister film, which is used for surface packaging of various types of panels. Therefore, it is also called decorative film and adhesive film, and is used in many industries such as packaging, building materials and medicine. The building materials industry accounts for the largest proportion, at 60%, followed by the packaging industry, as well as several other small-scale applications.
