The selectivity of 1,2-propanediol on the mixed carbon black-diamond electrode and the platinum electrode was 68% and 61%, respectively, with 88% glycerol conversion on the mixed carbon black-diamond electrode and 67% glycerol conversion on the platinum electrode. The authors propose a possible reaction mechanism for the formation of 1,2-PDO.

Jun 22, 2006· Titanate or zirconate coupling agents form a less than two nanometer monomolecular layer on the surface of any organic/inorganic. They chemically bridge non-silane reactive fillers such as CaC[O.sub.3], carbon black and silica, metal oxides, etc., with polymers.
This paper is focusing on mechanical properties of rubber toughened polyester filled carbon black (RPCB) for automotive parts and integrated circuits (IC) encapsulations appliions. The samples were fabried via hand lay-up and open molding technique in which 3 % of LNR was added as toughening agent in this composite and percentages of carbon black (CB) used vary from 0, 2, 4, 6, 8 and 10%.

Resistivity and dielectric constant of polyethylene/carbon black compounds were measured from room temperature to 140°C. Within the polyethylene melting region a PTC/NTC (positive followed by negative temperature coefficients) phenomenon is observed, whose intensity depends on the type of carbon black, its concentration and other parameters.
Keeping in mind the diverse requirements of the clients, we offer wide array of Carbon Black that are used as basic raw material in rubber industry and is used for fabriing conveyor belts, tubes and different other rubber products.They are finely processed using natural carbon deposits from our associates thereby ensuring its optimum quality.
It has been reported earlier that optimum loading of bonding agent is essential for proper bonding of fiber with rubber.6 When silica is replaced by black (mix E), scorch safety decreases but the maximum rheometric torque increases. This increase in torque cannot be the filler effect, because carbon black loading was only 5 phr.
Carbon Black Dispersant serves as excellent dispersant for carbon black and is used in black coating for improvement of jetness in the system. This type of additive with synergistic blend of surfactants in hydrocarbon solvent improves the processing of carbon black pigment.
Made from highly opaque, carbon black pigment, this ink offers excellent reproduction quality on absorbent surfaces with optimum lightfastness. Easily applied by pen, brush, steel brush or airbrush, Speedball’s India Ink is free-flowing, non-clogging and waterproof. Available in 2oz, 16oz and 32oz sizes.
Appropriate addition of acetylene black (AB) and pore-forming agent Na2SO4 could enhance the efficiency of CNTs-PTFE GDC. The optimum GDC composition was obtained by response surface methodology (RSM) analysis and was determined as CNTs 31.2 wt%, PTFE 60.6 wt%, AB 3.5 wt%, and Na2SO4 4.7 wt%.
