The unique properties of PVC (rainproof, fire-resistant, anti-static, easy to form), as well as the low input and high output characteristics of PVC.
PVC can be divided into soft PVC and hard PVC. Hard PVC accounts for approximately 2/3 of the market, while soft PVC accounts for 1/3. Soft PVC is generally used for the surface of floors, ceilings, and leather, but 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 range of use is limited. Hard PVC does not contain softeners, so it has good flexibility, is easy to form, is not brittle, is non-toxic and pollution-free, and has a long storage time. Therefore, it has great development and application value. The following text is abbreviated as PVC. The essence of PVC is a vacuum formed film used for surface packaging of various panels, so it is also known as decorative film or adhesive film, and 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, and several other small-scale application industries.
