The preparation of PAN-based ACFs was initiated in 1976 by Toho Rayon. Ltd and the use of pitch to obtain ACFs started in 1985, and these ACFs were commercialized by Osaka Gas Co. Ltd (AD ALL). Due to the low price of the pitch and high yield of the ACFs obtained, the manufacture of pitch-based ACFs has increased considerably, the pitch being one of the main precursors of ACFs nowadays [1]. 

At the beginning of the 1980s, interest became focused on developing ACF by the steam activation of conventional carbon fibres (CF), a fibril material whose main application was to reinforce polymer matrix composites. Poly-aciylo-nitril (PAN) based ACF was first produced by Toho Rayon Co. (Japan). At the end of the 1980s, interest centred on developing ACF from inexpensive precursors such as pitch based carbon fibres.

Amoco Performance Products Inc., Greenville, South Carolina, USA—acquired Union Carbide s carbon fiber production at Greenville, where a range of carbon fibers from pitch, cellulosic and PAN precursors were made under the trade name of Thornel. PAN precursor is also produced there. In the early 1990s, also acquired BASF s carbon fiber production. BASF, in 1985, had acquired the Celion carbon fiber production from Celanese at Rockhill, North Carolina. Meltspun PAN was also produced at Rockhill, but this was discontinued in favour of using precursor from Toho Rayon. Became BP Amoco and was purchased by Cytec Industries Inc.
