Carbon black.

In this solutions insert, a discussion of unique carbon blacks and their properties takes place. Many rubber chemists do not take advantage of all the unique properties that can be obtained by using the full range of available carbon blacks, according to the literature. Reluctance to inventory another black is said to be a contributing factor. Customers should be aware that they limit their compounds' properties by not making use of carbon blacks that may provide better physical properties, processing or dispersion than that of a run-of-the-mill black, according to the literature. Choosing a black that more precisely fits the product is said to sometimes mean meeting a specification, minimizing mixing problems or maximizing production efficiencies. This literature shows how to make better use of available standard ASTM carbon blacks. (Akrochem)
