1. Corrosion resistance: PVC has excellent corrosion resistance and can resist the erosion of various chemical substances such as acid, alkali, and salt. Therefore, it is widely used in fields such as chemical engineering and environmental protection.

2. Heat resistance: PVC has good heat resistance and can maintain stability at high temperatures, making it widely used in fields such as wires and cables, automobiles, and construction.

3. Flame retardancy: PVC has good flame retardancy and is not easily flammable, so it is widely used in fields such as wires and cables, construction, aerospace, etc.

4. Mechanical properties: PVC has excellent mechanical properties and can maintain strength and toughness at low temperatures, making it widely used in the manufacturing of products such as pipes, panels, and window frames.

5. Good insulation performance: PVC has good insulation performance and can be used as an insulation material for wires and cables.

6. Plasticity: PVC has good plasticity and can be made into various shapes and sizes of products through hot processing, injection molding, and other methods.

7. Environmental friendliness: PVC materials are relatively environmentally friendly compared to other plastic materials, with good recyclability and reusability.

In summary, PVC materials have excellent characteristics such as corrosion resistance, heat resistance, flame retardancy, mechanical properties, insulation performance, plasticity, etc., and are widely used in multiple fields such as wires and cables, chemical industry, construction, automotive, medical, home, etc.
