PVC particles can be divided into soft PVC and hard PVC

PVC particle hard board has good tensile, bending, compressive, and impact resistance, and can be used as a structural material alone. PVC particle 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. 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. However, due to the presence of softeners in soft PVC, it is prone to becoming brittle and difficult to store, thus limiting its range of use. 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 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.
PVC is polyvinyl chloride, a plastic product synthesized from 43% oil and 57% salt. Compared with other types of plastic products, PVC particles are more effectively used as raw materials, reducing fuel consumption. Meanwhile, the PVC manufacturing industry also has low energy consumption. And in the later stage of PVC product use, it can be recycled and converted into other new products or incinerated to obtain energy. Polyvinyl chloride has good electrical insulation properties and can be used as a low-frequency insulation material. Its chemical stability is also good. Due to the poor thermal stability of polyvinyl chloride, prolonged heating can cause decomposition, release HCL gas, and cause polyvinyl chloride to change color. Therefore, its application range is relatively narrow, and the operating temperature is generally between -15 and 55 degrees.
Stabilizers are added to PVC during production, but stabilizers can be classified as non-toxic or toxic. Only when toxic stabilizers such as lead salts are added can hidden dangers occur. But PVC products are mixed with good and bad, and some small businesses use lead salts as stabilizers, making it difficult to meet relevant hygiene standards. PVC particle products, whether injection molded or extruded, especially PVC material products with special requirements, strictly speaking, the performance of PVC material should be customer designed, specially designed to meet the different requirements of each user, and provide PVC solutions.
