Polyvinyl chloride (PVC) is a widely used synthetic thermoplastic polymer known for its versatility, durability, and cost-effectiveness. It is one of the most widely produced plastics in the world.
At Yumei, we provide precision CNC machining services to ensure high-quality, reliable results for a wide range of applications.
All machine shops should keep data on the properties of the thermoplastics and materials they use. The data helps in selecting the right material for a project and a material’s suitability for the end-use product. Below are some of the key characteristics of PVC:

| Advantages | Disadvantages |
| Durable and long-lasting | Lower heat resistance than engineering plastics |
| Resistant to moisture, chemicals, and corrosion | Can become brittle over time (especially rigid PVC) |
| Easy to process (extrusion, injection molding) | Environmental concerns related to additives and disposal |
| Low cost compared to many engineering plastics | Plasticizers in flexible PVC may raise safety concerns in some applications |
A：Yes.PVC is naturally flame-resistant and self-extinguishing, making it suitable for electrical and safety applications.
A: PVC typically supports continuous use up to around 60°C, depending on the formulation.
A: Yes. PVC has good weather resistance, but UV stabilizers are recommended for long-term outdoor exposure.
A: Yes. PVC has excellent resistance to acids, bases, and many chemicals, making it ideal for industrial environments.
A: Yes. PVC is highly resistant to moisture and water, making it suitable for piping and outdoor applications.
A: PVC is mainly classified into:Rigid PVC (uPVC)、Flexible PVC.
A: PVC (Polyvinyl Chloride) is a widely used thermoplastic material known for its corrosion resistance, insulation properties, and excellent processability.
A: PVC offers good processability but is temperature-sensitive and requires precise control.
