Rigid PVC FAQ
What is the difference between PVC and rigid PVC?
Polyvinyl chloride (بولي كلوريد الفينيل) is a general-purpose plastic material that can be divided into flexible and rigid types depending on its formulation. With the addition of plasticizers, PVC becomes flexible and is commonly used for cable insulation, hoses, and flexible products. بولي كلوريد الفينيل الصلب (uPVC) does not contain plasticizers, therefore it is rigid, strong, and has good dimensional stability, making it an ideal material for pipes, profiles, electrical conduits, and other rigid applications. Therefore, rigid PVC materials can be considered PVC materials with added plasticizers.
| Item | بولي كلوريد الفينيل (General) | بولي كلوريد الفينيل الصلب (uPVC) |
| Plasticizers | With or without plasticizers | No plasticizers |
| Flexibility | Flexible or semi-rigid | Rigid |
| Strength | Medium | High |
| Dimensional stability | Moderate | Excellent |
| Typical applications | Cable insulation, hoses, flooring | Pipes, profiles, conduits, sheets |

In what situations is it necessary to use polymer PVC compound materials?
When standard PVC compound raw materials cannot meet specific performance or processing requirements, PVC composite materials are needed. By mixing resin with additives such as stabilizers, الملدنات, lubricants, and fillers, PVC composite materials can achieve an ideal balance between flexibility, strength, heat resistance, and durability, thus meeting different application needs. Among them, PVC composite materials without added plasticizers are the rigid PVC composite materials introduced on this page.
- Cables and Wires: Flexibility, insulation strength, and flame retardancy of cable sheaths and insulation are achieved through plasticizers and stabilizers.
- Pipes and Fittings: Stabilizers and lubricants are added to traditional PVC raw materials to enhance the rigidity, brittleness, pressure resistance, and long-term outdoor performance of pipe fittings.
- Automotive Parts: Improve the impact strength, weather resistance and heat resistance of automotive interiors or wiring.
- Building Materials: Profiles, panels, doors and windows made of PVC composite materials, which improve their UV resistance, color stability and service life.
- Medical and Food Grade: Special non-phthalate plasticizers are added to ensure non-toxic, odorless, and flexible properties.
- Industrial Hoses and Flooring: combining abrasion resistance, flexibility, and chemical resistance, making them suitable for harsh environments.
