A very fine, very black powder, carbon black has a molecular and crystalline structure similar to graphite. It consists of primary particles (typically 10-50 nm) welded together into aggregates, also referred to as grape-like clusters (typically 50-250 nm).
Why Carbon Black?
One of the oldest manufactured products, dating back four thousand years, carbon black has been traditionally used over the centuries for its black pigmentation. In the early twentieth century, the reinforcing properties of carbon black on natural rubber were discovered, so that now, tires typically consist of 20 to 35% carbon black by weight. Carbon black is also an integral component of countless everyday products from pipes and other outdoor plastics to cables and batteries.
