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, plasticizers, lubricants, and fillers, PVC composite materials can achieve an ideal balance between flexibility, strength, resistencia al calor, 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: Flexibilidad, 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.
