5. Effects of Dispersants to Carbon Black 51. Viscosity and Gloss In general carbon black has large surface area, high oil absorption and low surface energy; it tends to be repellent to the vehicle and lose stability, such as significant increase in viscosity or reaggregation in the vehicle. In this case, the leveling, gloss, image ...

RUBBER GRADE CARBON BLACKS By: D. T. Norman Manager, Product Development Witco Corporation, Concarb Division Houston, Texas Over the years, many materials have been used as fillers in rubber compounds. In this sense, filler is a diluent and is used primarily to lower volume cost. With use, all fillers modify certain physical properties of the compound in addition to lowering cost. Therefore ...
The effect of peptizer on carbon blackrubber interaction in the internal mixer. Link/Page Citation ... This problem may be partly due to inadequate dispersion of the peptizer. It is recognized that breakdown at the more elevated temperatures is due to oxidative scission and that, in the lower temperature range and under the stresses set up during mastication, mechanical rupture of primary ...
The work described here is focused on methodology for reproducibly mixing carbon black with rubber in the laboratory, and reproducibility, but rapidly and easily estimating the degree of dispersion of the carbon black into the rubber as a function of mixing time. Procedures were developed for introducing rubber, filler, and other ingredients into a small, laboratory internal mixer and for ...
The second paper (Part II) was concerned with the kinetics of the dispersion of carbon black into natural rubber (dispersion quality as a function of mixing time) in an internal mixer. In this paper we consider the effects of changes in dispersion quality on the dynamic mechanical properties of both unvulcanized and vulcanized natural rubber. The effects of changes in the degree of carbon ...
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 surfaceareatovolume ratio, albeit lower than that of activated carbon.

In the second phase of this study, the effect of talc on the dispersion of carbon blacks with equal surface areas but different structure was evaluated. The carbon blacks of Group 2 (N326, N330 and N358) have a surface area of approximately 80 []/ gm. The structure, however, varies by a factor of two. The compounds were mixed using the ...

The effects of poly (vinyl pyrrolidone)(PVP) on dispersing carbon black (CB) particles were investigated by measuring Zaverage particle size, Zeta potential and centrifugal stability of CB dispersions. Addition of PVP in a dispersing medium significantly reduces the size of suspended CB particles, especially in water. The dispersing efficiency of PVP was found to have been enhanced by adding ...
