Conductive Carbon Black Printex 31 has been used as a conductive material in a wide range of products such as film, IC trays, heating sheet, magnetic tape, and conductive rubber. 

CAS No.1333-86-4

Electrostatic charge buildup can happen in any system in which two non-conductive materials move across and come in contact with each other. 

The discharge of this electrostatic buildup can lead to various hazards including flammable environments or failure of electronic equipment. 

To minimize these risks, many industrial rubber products have a specification on electrical conductivity to address the need for dissipation of electrical charges. 

Examples of rubber products with electrical conductivity or anti-static requirements are fuel hoses, conveyor belts, printing rollers, automotive belts or seals in sensitive electronic equipment. 

Carbon black type and loading greatly influence the electrical conductivity properties of a rubber compound

Applications of Printex 31:

Conductive rubber (electric wire, tandem belt)

Conductive plastic (IC tray, anti-static)

Heating sheet

Magnetic tape

Conductive Carbon Blacks are the most reliable and cost-efficient choice for producing conductive compounds. 

The conductivity efficiency of carbon blacks is related to primary particle size, structure and porosity. 

Small particle size blacks have a high surface area and higher inter-aggregate attractive force.

Mainly responsible for the conductivity are the carbon black properties like structure and surface. 

To create a conductive network, the chains of aggregates and agglomerate should built a network. 

In low pigment volume concentrations, this is fulfilled when the carbon black has a high structure. 

Higher structure allows the retention of a carbon network at low pigment volume concentrations. 

Therefore our grades offer unique properties like electrical and thermal conductivity. 

Nevertheless also other factors like the processing technology and mixing take a significant influence on the conductive efficiency of the compounds.

Conductivity is also related to the surface properties. 

In case of conductive carbon blacks with small surface areas, there is a good correlation between the conductivity and the graphitic constitution.
