how choose pvc compound

As an AI language model, I do not have personal preferences or opinions. However, here are some factors that can help in choosing PVC compound:

1. Application: The first step in choosing PVC compound is to determine the intended application. Different applications require different properties, such as flexibility, durability, chemical resistance, and UV resistance. For example, PVC compounds used in electrical cables require high electrical insulation properties.

2. Type of PVC: There are various types of PVC compounds, such as rigid PVC, flexible PVC, and semi-rigid PVC. Each type has its own characteristics and properties. For instance, rigid PVC is used for building materials, while flexible PVC is used for medical tubing and inflatable products.

3. Additives: PVC compounds can be customized by adding various additives, such as plasticizers, stabilizers, colorants, and fillers. These additives can enhance the properties of the PVC compound, such as increasing flexibility or improving weather resistance.

4. Processing method: The processing method used for the PVC compound can also affect the choice of the compound. For example, extrusion and injection molding require different properties and characteristics.

5. Regulatory compliance: PVC compounds used in certain applications, such as food packaging or medical devices, must comply with specific regulations and standards.

In summary, the choice of PVC compound depends on the intended application, type of PVC, additives, processing method, and regulatory compliance.
