Hello dear researchers :
Does anyone have a scientific report where the curve for the dependence of the Carbon Black content on the Electrical Tracking Resistance for, either a natural polyethylene, or an electrical semiconducting polyethylene, is shown ?
Best regards !
Hi
these papers can be articles that might be helpful:
- discusses the electrical resistivity of carbon black filled high density polyethylene and how it increases significantly when the composite is heated to the melting temperature."Electrical conductivity of carbon black–polyethylene composites: Experimental evidence of the change of cluster connectivity in the PTC effect"
- discusses the effect of carbon black on the thermoelectrical properties of poly(ethylene-oxide) composites and concludes that the composites behave electrically as semiconducting materials above room temperature."Effect of carbon black on the thermoelectrical properties of poly(ethylene-oxide) composites"
- discusses the electrical properties of polyethylene/polypropylene compounds for high-voltage insulation and how they are affected by factors such as oil resistance, rigidity, stiffness, and thermal stability."Electrical Properties of Polyethylene/Polypropylene Compounds for High-Voltage Insulation"
While these articles do not provide the exact information requested, they may still be useful for understanding the relationship between carbon black content and electrical properties in polyethylene composites.

I can provide you with general information on the relationship between Carbon Black content and Electrical Tracking Resistance in polyethylenes.
In polyethylene, especially in electrical insulating and semiconducting applications, the addition of Carbon Black is a common practice to improve electrical properties, including tracking resistance. The presence of Carbon Black particles can enhance the material's ability to resist electrical tracking, which is essential in electrical insulation.
The relationship between Carbon Black content and Electrical Tracking Resistance typically shows an improvement in tracking resistance as the Carbon Black content increases, up to a certain point. Beyond that point, the effect may plateau, or further increases in Carbon Black content may not significantly enhance tracking resistance.
The specific curve of this relationship can vary depending on several factors, including the type of polyethylene, the size and distribution of Carbon Black particles, and the processing conditions. Therefore, the exact curve would need to be determined through experimentation or by referring to published research studies specific to your material and application.
To find a scientific report or study that shows the curve for your particular polyethylene material, you may want to search academic databases, such as PubMed, IEEE Xplore, or Google Scholar, using keywords related to "Carbon Black," "Electrical Tracking Resistance," and the specific type of polyethylene you are interested in (e.g., "HDPE," "LDPE," "XLPE"). Additionally, you can reach out to researchers or experts in the field who may have conducted relevant studies.
