Knowledge of Conductive Plastics
Applications of Conductive ABS Compound
Metal fiber-filled conductive ABS compound
- Examples: Stainless steel fibers, etc.;
- Advantages: Good conductivity and mechanical properties. Metal fibers have a large aspect ratio and are more likely to form a conductive network in ABS, thereby improving conductive properties;
- Comparison: Compared with metal powders, metal fibers have better dispersibility;
- Limitations: Higher cost.
Filler Selection Comparison Table
| Filler type | Conductivity | Mechanical effect | Appearance effect | Cost | Typical applications |
|---|
| Carbon black | Good | Impact strength may decrease | Material turns black | Low | General anti-static/conductive parts, cost-sensitive projects |
| Carbon nanotubes | Good | Tensile/bending strength +20%–50% | Dark | Medium-high | High-strength, high-conductivity structural parts |
| Carbon fiber | Good | Strength, modulus, heat resistance improved | Dark | High | High-strength, high-heat-resistance parts |
| Metal fibers | Good | Good mechanical properties, excellent dispersion | Metallic/dark | High | High-conductivity, EMI shielding parts |
