Electrical insulation and cable sheathing require high-performance PVC compounds that meet specific demands such as flexibility, flame resistance, and insulation properties. We explore three key types of PVC materials used in electrical applications: Flexible PVC compounds for electric cables, Flame-retardant PVC sheath materials, and Custom PVC plastics for electrical insulation. Understanding their properties and benefits ensures optimal performance in various electrical systems.

1. Flexible PVC Compound for Electric Cables: Ensuring Durability and Ease of Installation
Flexible PVC compounds are widely used in electric cables due to their excellent bendability without cracking. These materials are formulated with plasticizers that enhance elasticity while maintaining electrical insulation.
Key Benefits:
High flexibility – Reduces risk of damage during installation in tight spaces.
Good dielectric strength – Prevents electrical leakage even under mechanical stress.
Weather resistance – Performs well in both indoor and outdoor environments.
Data Comparison:
| Property | Standard PVC | Flexible PVC |
|---|---|---|
| Tensile Strength | 15-25 MPa | 10-20 MPa |
| Elongation at Break | 100-200% | 200-400% |
| Operating Temperature | -10°C to 70°C | -20°C to 80°C |
Flexible PVC is ideal for wiring in automotive, household, and industrial applications where movement and bending are frequent.
2. Flame-Retardant PVC Sheath Material: Enhancing Fire Safety
Flame-retardant PVC compounds are critical in applications where fire hazards must be minimized. These materials contain additives that suppress combustion and reduce smoke emission.
Key Benefits:
Self-extinguishing properties – Stops burning once the flame source is removed.
Low smoke emission – Improves visibility during emergencies.
Compliance with safety standards (e.g., UL 94, IEC 60332).
Data Comparison:
| Property | Standard PVC | Flame-Retardant PVC |
|---|---|---|
| Oxygen Index (LOI) | 18-22% | 28-35% |
| Smoke Density (ASTM E662) | High | Low |
| Flame Spread Rating | Poor | V-0 (UL 94) |
These materials are essential in public buildings, transportation, and power distribution systems where fire safety is a priority.
3. Custom PVC Plastic for Electrical Insulation: Tailored Solutions for Specific Needs
Custom PVC compounds are engineered to meet unique requirements such as higher temperature resistance, UV stability, or chemical resistance.
Key Benefits:
Adjustable formulations – Can include additives for UV protection, anti-aging, or enhanced insulation.
Optimized cost-performance ratio – Reduces waste by matching exact application needs.
Industry-specific compliance – Meets standards like RoHS, REACH, and ISO certifications.
Common Customization Options:
High-temperature PVC (up to 105°C) for industrial motors.
UV-stabilized PVC for outdoor cable sheathing.
Anti-corrosive PVC for harsh chemical environments.
Custom PVC solutions ensure reliability in specialized applications, from renewable energy systems to underground cabling.
Selecting the right PVC compound depends on application requirements—whether it’s flexibility for easy installation, flame resistance for safety, or custom formulations for specialized performance. By understanding these material properties, manufacturers and engineers can optimize electrical systems for durability, compliance, and efficiency.
