An early form of carbon black produced by the burning of oils in a simple type of furnace. It was used in the compounding of rubber mainly as a black pigment it has little or no reinforcing effect.

The sophisticated application of the mechanistic and thermodynamic principles which have been worked out extensively over the last 10 years is really the basis of these technologies. From simple compounding of rubbers in hard polymers we have come to actual control over the mechanical behaviour as required by the foreseen application. For single polymer based systems this often leads to a specific combination of impact modifying additions. A simple case being the use of a combination of small and large rubber particles, socalled Binodal distribution. 

In the compounding of rubber formulations, many types of additives are used, some of which, such as antiozonants, are not usually included in polymer formulations. One of the earliest and most comprehensive procedures for the examination of vulcanisates was published by Zijp [114] in 1956. He subjected extracts of the vulcanisates to various preliminary treatments after which the compounding ingredients or their residues were separated and identified using paper chromatography. Somewhat later, Gaczynski and Stephen [115] published a paper chromatographic method for the identification of the accelerators most commonly used in Poland at that time. 

The effects this will have on the compounding of rubbers will be that more and more continuous mixing plants are commissioned, and fewer batch mixing plants. Continuous mixing of vulcanisable materials is also likely to see some inerease, particularly in the tyre sector as the smaller tyre eell production imits replace the present large tyre factories.
