[Chemical Knowledge]：Analysis of imported PVC is what material, you are worth understanding

With the continuous development of the global economy, the circulation and exchange of materials have become increasingly frequent. Among them, the circulation of various raw materials and products provides an important support for the icing on the cake in all walks of life. Among them, PVC is one of the widely used meta-chemical materials, and imported PVC is widely used in various fields. In this article, we will answer the question of imported PVC.

1. the basic properties of PVC

We need to understand the basic properties of PVC. PVC is a white or light yellow powder or granular solid, at room temperature is not active material. It has a certain toughness and stiffness, and can be formed into various shapes under certain conditions, and various formulations and processing techniques can make it have different properties.

PVC is a non-polar material insoluble in water and ethanol, with excellent corrosion resistance, insulation properties and mechanical strength, suitable for various applications. In addition, because PVC is a chemical synthetic material with petroleum and hydrochloric acid as raw materials, it has high environmental protection.

2. the characteristics of imported PVC

imported PVC, literally, you can know that this material is imported from abroad to domestic applications. In terms of specific characteristics, there is no special essential difference between imported PVC and domestic PVC, but in the following aspects, imported PVC is more excellent:

1. stable performance and high quality: imported PVC has higher quality standards and strict quality supervision from the selection of raw materials to the strict control of the production process. therefore, its performance is more stable and has better quality assurance.

2. Various colors and high transparency: Imported PVC pays more attention to the color depth in the manufacturing process, which can meet the requirements of different colors and transparency, and is suitable for more application scenarios.

3 high price, cost is not high: due to the different raw materials and manufacturing technology, the price of imported PVC is not lower than domestic PVC, in general, the price of imported PVC is higher than domestic PVC more than 50%, therefore, its cost performance is often not very high.

3. the manufacturing method of imported PVC

The manufacturing method of imported PVC is not much different from that of domestic PVC, mainly including the following steps:

1. Screening and preparation of raw materials: The raw materials required for the manufacture of imported PVC are relatively more advanced, requiring manufacturers to select high-quality raw materials from multiple suppliers

2. Mixing and processing: After selecting high-quality raw materials, imported PVC manufacturers will develop PVC formulations according to specific application requirements. Next, the raw materials are mixed in a large mixer and pulverized to a certain extent, and then molded by extrusion, compression, or the like.

3. Packaging and circulation: After the finished product is tested and inspected, it will be transported and sold.

4. the application scenarios of imported PVC

Because PVC has excellent performance and rich processing methods, it has a wide range of applications in all walks of life. Because of its excellent composition and processing technology, imported PVC is more helpful for its application in more advanced fields. Specifically, imported PVC is mainly used in the following fields:

1. Electrical industry: imported PVC can be used as wire, cable insulation materials, and wiring boards and other electrical accessories molding materials, with good insulation performance and mechanical strength.

2. Construction industry: In the construction industry, imported PVC can be used as manufacturing materials for decorative materials such as floors, wall panels, roofs and windows, and can also be used as manufacturing raw materials for important building materials such as drainage systems and waterproof methods.

3. Automobile manufacturing industry: due to the good mechanical properties and molding plasticity of PVC, it has become one of the important materials for manufacturing automobile interior and exterior decoration parts, interior facilities and driving information display equipment.

4. medical and health industry: in the medical and health industry, PVC can be used in the manufacture of infusion pipes, surgical instruments, medical bags and other medical supplies.

summary: Imported PVC is an excellent material with stable characteristics and excellent performance. It is widely used in electrical, construction, automotive, medical and other major industries. By understanding the performance and characteristics of imported PVC, we can not only make better application and purchase choices, but also provide more in-depth understanding and guidance for our future material selection.
