The structure of components ：
PVC can be divided into soft PVC and hard PVC. Among them, hard PVC accounts for about 2/3 of the market, and soft PVC accounts for 1/3.
Gram weight ：The thickness is between 25mm-65mm
Functions and uses：
The essence of PVC is a kind of vacuum blister film, which is used for the surface packaging of various panels, so it is also called decorative film and adhesive film, which is used in building materials, packaging, medicine and many other industries. Among them, the building materials industry accounts for the largest proportion, at 60%. Followed by the packaging industry, there are several other small-scale applications.
Characteristics of paper ：
PVC material has non-flammability, high strength, weather resistance and excellent geometric stability. Soft PVC accounts for 1/3. Soft PVC is generally used for floors, ceilings and leather surfaces, 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 use range is limited. Hard PVC does not contain softener, so it has good flexibility, easy to shape, not brittle, and long storage time, so it has great development and application value.
