In addition to the number of the paths, the intrinsic conductivity of the carbon blacks themselves, which is mainly a contact resistance, is of paramount importance. This picture is useful only if it is consistent with the various characteristics of electrically conductive rubber-carbon black compounds.
Apr 22, 2016· Carbon black is incorporated in polymers for permanent electrostatic charge protection, explosion prevention, and polymer applications that require electrical resistivities below 10 6 Ω cm. At the critical volume fraction of the carbon black grade, the carbon black-polymer compound percolates from an electrically insulating to a conducting domain.
Designing conductive compounds for extrusion applications, such as conductive vacuum hose or ESD packaging sheets, requires special attention to detail. Thin extrusion applications have strict physical property requirements which will be compromised if the conductive carbon is not consistently and uniformly dispersed.

Conductive carbon black is added to natural rubber or other materials to decrease their electrical resistance. For example: the conductivity of natural rubber is 10 15 Ωcm, whereas the conductivity of conductive rubber (natural rubber + conductive carbon black) is between 1-10 15 Ωcm.
Thermal black (Thermax) Carbon black is made from oil or coal, but Thermax is made from natural gas. And while carbon black usually makes rubber hard, Thermax has the unique ability to strengthen rubber while preserving its elasticity. This property is exploited in a variety of rubber goods, refractory materials, plastic goods and in metallurgy.
Since the conductive carbon black is priced higher to the conventional carbon black, this is a restraining factor adversely affecting the growth of the global carbon black market to a certain extent. In addition, conductive carbon black is considered as a potential carcinogen.
Carbon black is used in pigmentation, thermal materials, ultra violet protection, electrically conductive plastics, rubber, flow enhancement, static dissipation in non-conductive particles & …
Carbon black is the predominant reinforcing agent used to improve the processing, strength and durability of elastomer-based composites in most rubber applications. Our portfolio includes carbon black products specifically designed for tires as well as automotive and non-automotive industrial rubber products:
The low electrical resistance of vulcanizates loaded with conductive carbon blacks in a given particle size range is cause by the low density of the particles, high structure, or both. In addition, the smaller the particle size of the black, the lower the resistivity.

Carbon black (subtypes are acetylene black, channel black, furnace black, lamp black and thermal black) is a material produced by the incomplete combustion of heavy petroleum products such as FCC tar, coal tar, or ethylene cracking tar. Carbon black is a form of paracrystalline carbon that has a high surface-area-to-volume ratio, albeit lower than that of activated carbon.
