Conductive Carbon Black

Product Description

Carbon black with low or high resistance properties. Conductive carbon black can endow products with conductivity or anti-static effects. Its characteristics include small particle size, large and rough specific surface area, high structure, and clean surface (with few compounds). Conductive carbon black can be applied to different products, such as conductive rubber, conductive plastics, radio components, etc.

Conductive carbon black, as a functional and highly conductive filler, is mainly used in conductive and anti-static coatings, plastics, rubber, adhesives, inks, battery materials, cable shielding materials, etc. Conductive carbon black is widely used in the fields of conductivity, electromagnetic shielding, and anti-static in various industrial sectors such as electronics, electromechanical, communication, printing, papermaking, aerospace, and weapons

With the continuous development of the economy, the actual demand for conductive carbon black in the industry is constantly increasing, and its performance is very prominent. Therefore, Xinglongtai carbon black is very popular. Its products can be widely used in conductive and anti-static rubber and plastic products, internal and external shielding cable materials, anti-static oil, water-based coatings, high-end car ignition wires, and anti-static plastic fuel tanks. Various rubber and plastic sealing strips, component filling and dyeing reinforcement agents. So, how much do you know about the chemical properties of its products? Now let's listen to industry experts give you a detailed introduction.

The production methods of highly conductive carbon black vary, and their surface chemical properties vary. The surface of carbon black has different oxygen-containing functional groups (such as carboxyl, lactone, phenolic, carbonyl, etc.). Carbon black with high oxygen-containing functional groups generally has high volatility, good color tone adjustability, and high fluidity. After heating the carbon black sample to 825 ± 25oC, the volatile matter of carbon black is expressed as a percentage weight loss. The more oxygen-containing genes in carbon black, the greater the volatile content.
Moisture absorption and density: Carbon black is a substance with a large surface area, therefore it has a certain degree of moisture absorption. The moisture absorption of medium carbon black is mainly determined by the size of the surface area. Measures can be strengthened, especially in the packaging, storage, and transportation processes, to reduce the moisture absorption of the product. Due to the inconvenience caused by excessive moisture absorption during the processing, special packaging is required for certain types of carbon black. Whether powdered or granular pigment carbon black is used for a given plastic blend depends on the type of dispersion and the characteristics of the resin, but processing ability is also an important factor. Currently, most dispersion equipment can exert shear force, which is sufficient to evenly disperse the particles.
