Cleveland-based compounder PolyOne Corp. will manufacture a line of polymers that conduct electricity, from GeoTech Chemical Co. LLC of Tallmadge, Ohio.
Plastics normally act as a natural insulator, stopping the flow of electricity. But so-called inherently conductive polymers allow electricity to pass through, similar to metal.
PolyOne has exclusive rights to manufacture and market GeoTech's Teslart brand of inherently conductive polymers. Teslart can be combined with solvent- or water-based resins, then injection molded and extruded. Applications include corrosion-resistant coatings, anti-static fabrics and packaging, electronic shielding, electrical products, conductive inks and adhesives.
Also under the agreement, PolyOne will make GeoTech's Catize line of additives for use in paints and coatings to prevent corrosion.
Teslart uses a polymer based on lignosulfonated polyaniline, dubbed Ligno-Pani, to make it conductive. The Teslart name is a reference to inventor Nikola Tesla, the electricity pioneer who created man-made lightning.
Several years ago, GeoTech licensed two Ligno-Pani patents from NASA Kennedy Space Center in Florida. The material is made by grafting polyaniline chains to lignin, which is a byproduct of the pulp and paper industry.
Seegott Inc., a specialty chemical distributor based in Streetsboro, Ohio, will continue to distribute Teslart and Catize products.
PolyOne displayed the Geotech conductive polymers and corrosion-resistant additives at NPE 2003.
