The present disclosure provides a functionalized carbon black obtained by treating an oxidized carbon black with a sulfur-containing primary or secondary amine or a salt thereof. The disclosure also relates to a process for preparing such functionalized carbon black. Furthermore, the present disclosure relates a vulcanizable rubber composition including (i) a vulcanizable rubber component, and (ii) an oxidized carbon black and (iii) a sulfur-containing primary or secondary amine or a salt thereof, or a functionalized carbon black formed from these components. The disclosure also concerns an article made from the vulcanizable rubber composition. The functionalized carbon blacks disclosed herein are particularly useful for obtaining rubber compounds with low hysteresis and enhanced abrasion resistance, e.g. for the production of energy-saving tires.

Functionalized carbon black, preparation thereof and use in vulcanizable rubber compositions

The present invention relates to a furnace black having a STSA surface area of at 130 m/g to 350 m/g wherein

Process for controlling the porosity of carbon blacks

The present disclosure provides polymeric compositions with balanced electrical and mechanical properties exhibiting reduced hysteresis comprising an electrically insulating polymeric material, a first carbon black material having a statistical thickness surface area (STSA) of below 70 m/g and an oil absorption number (OAN) in the range from 70 to 150 mL/100 g, and a second carbon black material having a statistical thickness surface area (STSA) of at least 100 m/g and an oil absorption number (OAN) of at least 150 mL/100 g, wherein both carbon black materials are included in an amount below its respective percolation threshold concentration, with the total amount of the first carbon black material and the second carbon black material being sufficient to render the polymeric composition antistatic or electrically conductive. The polymeric compositions exhibit balanced electrical and mechanical properties and a reduced hysteresis. The disclosure also relates to a process for preparing such antistatic or electrically conductive polymeric compositions and articles produced from such compositions.

Antistatic or electrically conductive polymeric composition with reduced hysteresis

Suggested is a carbon black composition showing a narrow Aggregate Size Distribution (ASD) characterized by a &#x394;D/Dvalue of about 0.58 to about 0.65 and a Relative Span (D&#x2212;D)/Dof about 0.5 to about 0.8, which is obtainable by means of a modified furnace reactor. The composition shows superior additive performance and allows producing e.g. bus or truck tires with improved wear resistance and reinforcement.

Carbon black compositions

The invention relates to a carbon black with a CTAB surface area of from 20 to 49 m/g, with a COAN greater than 90 ml/(100 g), and with a sum of OAN and COAN greater than 235 ml/(100 g). The carbon black is produced in a furnace reactor, where from 20 to 55% by weight of the feedstock used for the carbon black are introduced radially through a nozzle within the first third of the reaction zone, and the remaining amount of the feedstock used for the carbon black is introduced through a nozzle upstream at least one further point into the reactor. The carbon black can be used in rubber mixtures.

Carbon black, method for the production thereof, and use thereof

The invention relates to black having a CTAB surface area of 100 to 160 m?/g, a quartile ratio of more than 1.60, and an FP index of &#x3e;0. Said black is produced in a furnace reactor. Sixty to 90 percent by weight of the raw black material are injected into the reactor in the first third of the reaction zone, while the remaining amount of the raw black material is injected into the reactor upstream at least in one other point. In addition, the combustible is conducted such that 90 to 100 percent by weight of the combustible are evaporated when first hitting the raw black material and 80 to 99 percent by weight of the combustible are evaporated 5 ms before hitting the raw black material. Said blacks can be used in rubber mixtures.

Black, method for the production thereof, and use thereof

Electrocatalyst which are formed of a carbon support, which is a carbon black with an H content of >4000 ppm and, as the catalytically active component, platinum or bi- or multi-metallically doped or alloyed platinum. The electrocatalysts are prepared by deposition of noble metals on the carbon black surface. They can be used for the production of fuel cells.

Electrocatalyst for fuel cells

An organosilane preparation, comprising a mixture of one or more organosilanes and one or more fillers, has a fines content of less than 2%.

Granular organosilane preparation, process for the production thereof and use thereof

Carbon black characterized by a STSA surface of between 20 and 180 m /g, a 24M4-DBP absorption of between 40 and 140 ml/100 g, a specific BET surface of between 20 and 250 m /g, a content of 0.01 to 20 wt. % of silicon, referred to its overall weight, and a tan &dgr; /tan &dgr; ratio greater than 3.37&minus;0.0068 STSA is produced by mixing silicon-containing compounds with the carbon black raw materials in the oxidative pyrolysis of the carbon black raw materials and optionally using carbon black oil as fuel. The carbon black can be used as a filler in rubber mixtures, preferably for tires.

Carbon black

Inversion carbon blacks and a method for their manufacture are disclosed. The inversion carbon blacks have a lower rolling resistance with identical or improved wet skid behavior. The particle size distribution contains a smaller proportion of particles with large diameters. This leads to an improved abrasion behavior of rubber compounds which were prepared using these carbon blacks. The inversion carbon blacks can be manufactured in conventional carbon black reactors by controlling the combustion in the combustion chamber in such a manner that carbon black nuclei form, which are immediately brought into contact with the carbon black raw material. The carbon blacks present a lower proportion of larger particles if the additions of combustion air and carbon black raw material are increased in an appropriate manner.

Inversion carbon blacks and method for their manufacture

A process for continuous dry granulation of powdered carbon black. Granulation is performed with the assistance of a granulator. As a result, for comparable sized equipment, the carbon black throughput can be increased several times as compared with pelletizing drums used in the conventional manner.

Process for continuous dry granulation of powered carbon black

Carbon black pellets which can be produced by the addition of wax during dry granulation of carbon black powder. The carbon black pellets are distinguished by a pellet hardness of at least 0.15 N with a wax content of less than 10 wt. %, based on the total weight of the carbon black pellets.
