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)
