A composite polymer composition comprising partially crystallized carbon black. The composition exhibits superior thermal transfer properties in plastic formulations. The polymer precursor exhibits excellent rheology when compared to similar compositions comprising traditional carbon blacks. The composite polymers provide for higher loading of more thermally conductive carbon blacks in a variety of composite polymer compositions.

Thermally conductive polymer compositions containing carbon black

Disclosed herein are high structured carbon blacks, methods of synthesis and treatment, and dispersions and inkjet ink formulations prepared therefrom. The carbon black can have the following properties: OAN&#x2267;170 mL/100 g; and STSA ranging from 160 to 220 m/g. The carbon black can also have the following properties: OAN&#x2267;170 mL/100 g; and a ratio of STSA/BET surface area ranging from 0.7 to 1.

Carbon blacks

Novel furnace carbon blacks that impart advantageous properties to rubber and plastic compositions and may be utilized in place of lamp blacks, thermal carbon blacks and blends of carbon blacks. Also disclosed are novel rubber and plastic compositions incorporating the novel carbon blacks which exhibit advantageous combinations of compound processing and physical performance properties.

The present invention includes metal oxide foam particles and a method of making the same. A decomposable metal salt feed solution is injected into a hot atomizing gas. The mixture of hot atomizing gas and feed solution is maintained in the reactor until the feed solution converts to metal oxide foam particles. The metal oxide foam particles have a high specific surface area.

Novel carbon blacks having an I.sub.2 No. of 26-34 mg/g; a CTAB of 26-34 m.sup.2 /g; a Tint of 46-54%; a DBP of 61-69 cc/100 g and a Dst/Dmode ratio of 1.31-136. Preferably the carbon blacks are additionally characterized by having a Number Median (D.sub.c /D.sub.p) of 2.7-3.1. Also disclosed are novel rubber and plastic compositions which, when the novel carbon blacks are incorporated therein, have lowered viscosity properties during subsequent processing.

Carbon Blacks

A process for preparing carbon blacks having lower-than-normal structure at a given surface area, and lower-than-normal surface area at a given overall combustion level. The process is carried-out by adding auxiliary hydrocarbons, which is hydrogen or any hydrocarbon having a molar hydrogen-to-carbon ratio greater than the molar hydrogen-to-carbon ratio of the feedstock, to the reaction zone of a carbon black reactor and adjusting the primary combustion and overall combustion so that the SSI of the process is less than zero.
