Introduction
Carbon black is an engineered compound made – in the case of product from VALETIME – from a coal-based feedstock derived from coke making and known as anthracene oil.
Anthracene oil is heated in a specially designed furnace, to produce a gas stream laden with carbon black powder. The gas stream passes through a series of filters, where the carbon black is separated from the gases. The carbon black powder then is bound with water to create larger beads or granules, which are passed through a dryer and packaged for delivery to customers in every part of the world.
Carbon Black is an essential ingredient in tyres and other mechanical rubber products, improving their strength, durability and overall performance. It also is used as a pigment in printing inks, paints and plastics.
Main Markets for Carbon Black produced for VALETIME are:
- Tyre Industry – supplier to major World producers of vehicle tyres
- Rubber Industrial Products – includes manufacturers of beltings, footwear soles, electrical cables, coatings etc.
- Polygraphic Products – particularly in newspaper inks and other special printing inks.
- Plastics – used as a base pigment in master batches.

Specification – “K-Series”
Kremenchug produces active and semi-active carbons from anthracene oil ( derived from coke production using local coal ) to 5 GOST standard ( Russian ) Grades and 9 ASTM grades.
Anthracene oil is heated in a specially designed furnace, to produce a gas stream laden with carbon black powder. The gas stream passes through a series of filters, where the carbon black is separated from the gases. The carbon black powder then is bound with water to create larger beads or granules, which are passed through a dryer and packaged for delivery to customers in every part of the world.

Summary of K-Series Specification – further details in full specfication sheet
A distinct feature of Carbon Black from Kremenchug is the final form of product – being “granules” ( = microcrystaline ) as a result of further processing of the fine powders ( “dust” or typical “soot” ) output from production. ( Note product is not “encapsulated” but formed into large granules or pellets by mechanical process. ) This provides for much cleaner and relatively dust-free handling in use.
FOOD CONTACT APPROVAL
In May 2005, Carbon Black grades N220 and grades N330 successfully passed tests for heavy metal content, carried out by RAPRA, in accordance with EU Resolution AP (89) 1. They are therefore suitable for use in masterbatch intended for use in contact with foodstuffs – specifically in accordance with European Resolution AP (89) 1 on the use of colourants in plastic materials coming into contact with food.
Copies of Food Contact and Heavy Metal Content certificates are below, along with a copy of the RAPRA report.
Source – “K-Series”
Carbon black for VALETIME is produced at KREMENCHUG Carbon Black Plant – the most modern of 2 plants in the Ukraine.
Production at Kremenchug dates from 1965, was first expanded in 1975 and progressively developed since – culminating in the mid-1990’s in preparations for privatisation in May 1996.
Produces active and semi-active carbons from anthracene oil ( derived from coke production using local coal ) to 5 GOST standard ( Russian ) Grades and 9 ASTM grades.
The plant is 98% automated. Capacity ( 1996 ) 115 Million tonnes.
ISO 9002 certified in July 1998 ( from KZTV THO Netherlands )

Toxicology
IARC evaluation: possible human carcinogen (Group 2B). May be harmful by ingestion or inhalation. Respiratory irritant. Typical STEL 7 mg/m3. Note: Carbon black is generally made under controlled conditions, and has a high carbon content. By contrast, soot usually contains additional complex organic molecules, some of which may be carcinogenic. Thus, industrial and domestic soot may be presumed to present a greater risk to human health than commercially-produced carbon black.
Personal protection
Safety glasses, adequate ventilation.
