So what exactly is PVC? PVC, also known as Polyvinyl chloride, is mainly composed of polyvinyl chloride. Other components are added to enhance its heat resistance, toughness, and ductility. The top layer of this surface facial mask is paint, the main component in the middle is PVC, and the bottom layer is back coating adhesive. It is a beloved, popular, and widely used synthetic material 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 average production and consumption of PVC is 1.4 million tons. PVC is being produced and applied worldwide at a growth rate of 4%. The growth rate of PVC in Southeast Asia is particularly significant, thanks to the urgent need for infrastructure construction in various Southeast Asian countries. Among the materials that can produce 3D surface facial mask, PVC is the most suitable material.
PVC can be divided into soft PVC and hard PVC. Hard PVC accounts for approximately two-thirds of the market, while soft PVC accounts for one-third. Soft PVC is generally used for the surface of floors, ceilings, and leather. However, due to the presence of softeners in soft PVC (which is also the difference between soft PVC and hard PVC), it is prone to becoming brittle and difficult to store, so its scope of use is limited. Hard PVC does not contain softeners, therefore it has good flexibility, is easy to form, is not easily brittle, is non-toxic and pollution-free, and has a long storage time. Therefore, it has great development and application value. PVC is commonly referred to as PVC in the following text. The essence of PVC is a vacuum plastic film used for surface packaging of various panels, also known as decorative film or adhesive film, which is applied in many industries such as building materials, packaging, and medicine. The building materials industry accounts for the largest proportion at 60%, followed by the packaging industry, as well as several other industries with small-scale applications.
