Polyaniline Powder ORMECON

Polymers that conduct electric currents without the addition of conductive (inorganic) substances are known as "intrinsically conductive polymers" (ICP). Polyaniline (PAni) is the first polymer of this kind to achieve unlimited world-wide commercial availability. PAni is the first dispersible ICP and has been developed by Zipperling Kessler & Co. Besides our production in Ahrensburg, it is also commercially produced on the basis of a license by Zipperling on a pilot plant by Allied Signal in Buffalo (N.Y., USA). PAni is marketed under the trade name "ORMECON".

Polyaniline as a pure powder is insoluble neither fusible. It can only be processed by dispersion. Zipperling offers dispersions in polymers, lacquers and solvents. For industrial use, these dispersions are available as a ready to use product or as a concentrate.
