The characteristics and advantages of polyvinyl chloride (PVC)

I. Characteristics

1. High Durability & Chemical Resistance
   PVC exhibits exceptional resistance to acids, alkalis, oils, and solvents, making it indispensable for building pipelines, industrial fittings, and chemical storage tanks.

1. Versatility & Processability
   PVC can be molded into diverse shapes and sizes via extrusion, injection molding, or calendering.

   • Rigid PVC: Used in construction materials (e.g., window frames, pipes).
   • Flexible PVC: Applied in wires/cables, flooring, and synthetic leather.

2. Weather Resistance & Flame Retardancy

   • Withstands prolonged outdoor exposure to UV radiation, moisture, and temperature fluctuations.
   • Self-extinguishing properties comply with fire safety standards, ideal for fire-sensitive environments.

3. Sustainability & Recyclability

   • Long service life and compatibility with modern recycling technologies reduce environmental impact.

II. Advantages

1. Cost-Effectiveness

   • Low raw material and production costs enable widespread industrial and commercial applications.

2. Ease of Processing

   • Adapts to various manufacturing techniques (e.g., blow molding, thermoforming) for customized solutions.

3. Biocompatibility (Medical Applications)

   • Used in blood bags, IV tubing, and medical packaging due to non-reactive, sterile properties.

4. Superior Electrical Insulation

   • Protects wires and cables as an insulating barrier, ensuring safety in electrical systems.

5. Adjustable Mechanical Strength

   • Enhanced with additives (fillers, plasticizers) to balance rigidity and flexibility for specific needs (e.g., hoses, gaskets).
