CARBON BLACK

carbon black sadze sadzy сажи технический углерод

Carbon black, obtained by various methods (furnace, thermal, acetylene, channel etc.), is consitituted by carbon being a product of partial thermal decomposition of hydrocarbons.

Since decades carbon black paid attention of scientists and maufacturing companies because of its favourable properties as a rubber goods filler (so-called reinforcing filler). Incorporating of CB entails obtaining of homogenous, black coloured rubber compounds with parallel enhancement of rigidity and fracture resistance of the vulcanizates. Tremendous impact of the blacks has been reflected in the classification of the grades on the basis of intrinsic parameters (manufacturing method, average particles size, specific surface area, pH and so forth). In example, particle diameters may vary from 20 nm in case of some furnace blacks up to several hundreds nm for thermal ones. These particles inherently arrange into aggregates, viz. the smallest individuals dispersible in polymer matrix (having sizes up to microns) and bigger agglomerates (e.g pellets of magnitude of few milimeters).

Appropriate legislative actions had to be taken due to the presence of organic impurities (mainly PAH), absorbed on the CB surface. These naturally occur as a by-product of partial combustion. As a result, carbon black producers began to to implement alternative routes of syntheses, along with more strict control over processes being carried out. In spite of organic residues do not significantly influence on reinforcing characteristics of black, environmental issues and health hazards play the crucial roles. As of inorganic impurities, which are resultant of final manufacturing stages, they are often find to favour rate of curing, being higher for high pH of carbon black. Besides that, concentration of oxygen-containing moieties on the surface and unsaturated bonds corresponds to the way how rubber curing proceeds.

Wide assortment of carbon blacks offered by Polsaros Sp. z o.o. (conventional, specialty, odourless, pyrolytic), guarantees effective choice accoriding to Customers needs. Each grade fulfills the highest standards, as advocated in international and technical norms, as well as in law regulations and legislation.

Pyrolytic carbon black

One of the many possibilities how to utilize pyrolytic carbon black is manufacturing of activated charcoal. It is also applied as an igredient of pigments used in textiles, production of leather, fur, paper, small-scale chemicals, plastics, other non-metal mineral goods such as plasters, cements. As an important raw material in large-scale chemical industry including petroleum based substances, non-noble metals, end use metal commodities, excluding devices and machines. Pyrolytic grades play essential role in fire resistant products, as a reinforcing filler in low quality rubber goods, part of road surface formulations and as potential solid fuel with high calorie content.
