PVC particles can be divided into soft PVC and rigid PVC

PVC particle hard board has good tensile, bending, compressive and impact resistance and can be used alone as structural material. PVC soft board, elongation at break and cold resistance will increase, but brittleness, hardness and tensile strength will decrease. 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. Soft PVC is generally used for the surface of floors, ceilings and leather. However, soft PVC contains a softener, which 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 form, is not brittle, non-toxic, 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 building materials, packaging, medicine and so on. Among them, the building materials industry accounted for the largest proportion, 60%, followed by the packaging industry, and several other small-scale applications.
   PVC is polyvinyl chloride, a plastic product synthesized from 43% oil and 57% salt. Compared with other kinds of plastic products, PVC particles are more effective in the application of raw materials, reducing fuel consumption. At the same time, the energy consumption of the PVC manufacturing industry is also very low. And in the later stages of the use of PVC products, it can be recycled and converted into other new products or incinerated to obtain energy. Polyvinyl chloride has good electrical insulation properties, can be used as a low-frequency insulation material, and its chemical stability is also good. Due to the poor thermal stability of polyvinyl chloride, long-term heating will cause decomposition, release HCL gas, and discolor the polyvinyl chloride. Therefore, its application range is narrow, and the use temperature is generally between -15 and 55 degrees.
PVC will be added to the stabilizer during production, but the stabilizer is non-toxic and toxic. Only when a toxic stabilizer such as lead salt is added will it cause hidden dangers. However, PVC products are mixed, and some small enterprises use lead salts as stabilizers, and it is difficult to meet relevant health standards. PVC pellet products, whether injection molding or extrusion, especially PVC materials with special requirements, strictly speaking, the performance of PVC materials should belong to Customer-designed, especially designed to meet the needs of each user, providing PVC solutions.
