Achieving High Electrical Resistivity in Rubber Compounds

One often associates carbon black with electrical conductivity, and the presence of carbon black in rubber insulating compounds has been regarded as detrimental in this aspect. But what if we need carbon black performance properties but also high electrical resistivity?

Carbon Blacks in Inkjet: Particle and Aggregate Size Considerations

Inkjet inks utilizing waterborne, solventborne, and energy curable chemistries have become popular in recent decades compared to more traditional analogue printing techniques due to the ability to print variable content, low ink usage, and versatility of substrate types and geometry. Compared to dyes, which have been used extensively, particularly in waterborne systems due to their solubility, pigments offer much better lightfastness, water/solvent resistance, holdout (especially on porous substrates), and color performance.

Improving the Performance of Lithium ion Batteries with Conductive Carbons

First commercialized in the early 1990s, lithium ion batteries have since come to be an integral part of modern life. Portable electronic devices, such as cell phones, laptops, and power tools, were the first to utilize this technology. In recent years, the push to electrify personal transportation has accelerated the production of electric vehicles. Conductive carbons are now further improving the performance of Lithium ion batteries.

The Roles of Carbon Black in Wire & Cable Conductor, Insulation and Jacketing Applications

Conductive plastic compounds have a variety of applications including conductor and insulation shield for wire and cables, antistatic, electrostatic dissipation (ESD), electromagnetic interference (EMI) shield, and metal replacement.  This blog talks about the key properties of carbon black and how they are related to conductivity performance, especially as it relates to wire and cable applications.

Formulating Carbon Black in Adhesives & Sealants

When qualifying a new carbon black in a new product or as a potential offset, it is critical to understand the Performance Triangle by looking at carbon black selection, formulation and dispersion.

Publication Gravure Ink Performance and the Role of Carbon Black

Carbon blacks are frequently used in publication gravure inks and a specific product needs to be selected to meet the desired performance needs. Balancing the properties of a carbon black will deliver the required colour density, jetness, gloss and rheology. The carbon black portfolio of Birla Carbon has a range of products to meet different jetness and tonal needs.

Maximizing the Fatigue Performance of Rubber Components

Across a vast range of industries, rubber components play safety critical roles in activities every single day. As such, rubber components need to be durable and long lasting. While there are many ways in which a rubber component can fail in service, mechanical fatigue is probably the most common failure mechanism which affects nearly all rubber-based components.

Color Space Definition for High Jetness Automotive Coatings

Defining the targeted color space is an important first step in having meaningful discussions on changes to coatings formulations that will achieve the desired end result. If a customer says they want to be bluer in undertone, then the immediate question becomes bluer compared to what?

Instrumental Measurement of Deep Black Coatings

There are a lot of instruments involved in the measurement of deep black coatings. In this blog post, Dr. Richard Abbott provides insights on what measurements and specifications are used to receive accurate and precise measurements of black objects.

Maximizing Curing of UV Inks and Coatings with Carbon Black

UV-curable inks and coatings are a high growth market for various industries such a printing ink, particularly for food packaging, floor coatings, and 3D printing. These materials offer high gloss, low/zero VOC (volatile organic compound), and many other advantages compared to other liquid chemistries.

Frequently Asked Questions

Carbon black refers to engineered carbon nanoparticles that are fused together to form unique 3-dimensional aggregates. Carbon black, in its pure form, is a fine black powder. It is produced by partial burning and pyrolysis of oil residues or natural gas at high temperatures under controlled process conditions. Carbon black is different from charcoal. Carbon black has a complex particulate structure that is formed in a gas phase produced from fully pyrolyzed hydrocarbons at high temperatures. Charcoal is produced by the pyrolysis of wood or other carbonaceous materials at lower temperatures and is in bulk or milled powder form. Due to their structural and morphological differences, they have distinctly different performances.
Carbon black is usually made from hydrocarbon oils, e.g., refined coal tar or heavy petroleum oil, or natural gas. Hydrocarbons derived from recycled tires, and biomass, e.g., wood, etc., are gaining increasing attention as sustainable sources of feedstock.
Carbon black is a vital component in making many of the products we use every day strong, appealing, durable and safe. Some of these solutions include tires, automotive weatherstrip and belts, plastic parts, coatings, inks and sealants. For example, tires without reinforcing carbon black would not run over 100 miles. As a pigment, carbon black offers desired color strength for applications ranging from electronic enclosures to automotive coatings, and household appliances. Carbon black imparts UV durability to rubber and plastic goods to ensure their service life for a few decades. As an electrically conductive additive, carbon black renders insulative rubber and plastic materials antistatic, electrodissipative or conductive to provide safety and protection, and thereby reliability for mining, electronic packaging, and wire and cable applications, to name a few.
