Grade Description Field of application Uses
N-990 This is obtained by thermal decomposition of natural gas in batch furnaces without access for air. It belongs to low active grades of carbon black and is characterized by the most low values of specific surface and structure index in comparison with other grades. It is made inpellet or powder form. For rubbers Ensures excellent technological properties of rubber mixes while processing, possibility to attain a high degree of filling of polymeric composition thus used for manufacturer of conveyor belts, as inactive filler for tyres, industrial rubber goods with a high content of the filler.
For carbon graphite materials It graphitizes well. Along with the strenghtening effect it ensures a high conductivity of articles. It shows a low gas emission during heat treatment. It gives good technological properties to mixes.
N-772 It is obtained in a continuous process in the furnace by a thermal-oxidative decomposition of natural gas. It belongs to semiactive grades of carbon black and it shows low values of dispersion and structural features. It is made in pellet form.  For rubbers Good dynamic properties to rubbers with a relatively low dispersion are imparted by this grade of carbon black. It allows to obtain an optimum combination processing of mixes. It is used in manufacture of frameworks, extruding rubber articles, tube, rubber articles subject to dynamic loads. It is also used as a semiactive filler in production of the industrial rubber articles, it is used in masterbatch.
For paintwork materials and for painting polymeric materials It is used to give a black tint in the mix for printing ink, as a pigment for plastic materials, UV - stabilizer for polyolefins. This grade of carbon black is one of major components of masterbatch which is used for pigmenting.
K-354 This is obtained by a channel mode in a diffusive flame during a thermal-oxidatative decomposition of natural gas. It belongs to active graded of carbon black and it has a high dispersion value and a low structural value. It is a highly dispersive and enhancing filler and a pigment. It is made in pellet form. For rubbers Makes rubber mixes resistant to premature vulcanization. Makes vulcanizate and articles strong when static and dynamic loads are applied. It is used for production of extra strong industrial rubber goods.
For paintwork materials,  painting of polymeric materials and for perfumery It disperses well and forms highly stable dispersions. It ensures an intensive black colour of materials, excellent apperance of coats, resistance of painting to the ultraviolet radiation. It is used for making intensively black varnishes and coast, synthetic fibres, printing ink, carbon paper, typewriter tapes, in perfumery for making the eyelash ink.
K-163
K-173-0
 The pigment carbon black is obtained by the channel method by setting carbon black particles which are performed in the diffusion flame with an incomplete combustion of natural gas, on a metal surface with a further oxidation (K-173-0) or without oxidation. These belong to special highly black grades of the carbon black and they are characterized by a high dispersion value and a high content of volatiles. For carbon graphite materials This gives a good enhancing effect due to a high dispersion ability and an active surface. It is highly pure from the point of view of content of mineral admixtures.
For paintwork materials,  painting of polymeric materials and for perfumery These are high quality ultra dispersing black pigments which ensure a high depth of black colour of the paintwork and impressions, resistance of the paint to the ultraviolet radiation, lustre of the nitrocellulose enamels for cars. These disperse well and highly stable dispersions are obtained as a result of this. They are used for making paints, varnishes, painting ink, rolling paste for printing arts, carbon paper for eyelash ink.
