New conductive additives give better ESD control.New conductive additives from Eeonyx Corp., Pinole Pinole (pĭnōl`), city (1990 pop. 17,460), Contra Costa co., W Calif., on San Pablo Bay; inc. 1903. Primarily residential, it manufactures concrete and chemicals. , Calif., are said to offer better resistivity resistivity Electrical resistance of a conductor of unit cross-sectional area and unit length. The resistivity of a conductor depends on its composition and its temperature. control and come in a range of colors. Eeonomer additives are carbon blacks coated with inherently conductive polymers (ICPs)-polypyrrole or polyaniline. In-situ polymerization polymerization Any process in which monomers combine chemically to produce a polymer. The monomer molecules—which in the polymer usually number from at least 100 to many thousands—may or may not all be the same. of the resin on the carbon black reportedly provides much greater thermal stability (up to 572 F) than typical ICPs alone, thus allowing use in a wider range of resins. New Series 700 and 800 compounds reportedly allow for much better control and reproducibility of conductivity than does carbon black alone. In some resins (ABS, nylon, polyesters) only half as much Eeonymer reportedly is needed to obtain the same level of conductivity as with carbon black, and less sloughing results, as well. In heterogeneous alloys like TPOs, Eeonomer is said to produce 10-fold higher conductivity than an equal loading of carbon black. Eeonyx has expanded its product line by custom blending with other powders to create a range of resistivities and colors, from light gray to green and light brown. These are mostly aimed at ESD (1) (Electronic Software Distribution) Distributing new software and upgrades via the network rather than individual installations on each machine. See ESL. flooring laminates. The company also offers EeonTex conductive fabrics of glass, quartz, or Kevlar coated with polypyrrole, polyaniline, or polythiophene. These can be used in thermoset A polymer-based liquid or powder that becomes solid when heated, placed under pressure, treated with a chemical or via radiation. The curing process creates a chemical bond that, unlike a thermoplastic, prevents the material from being remelted.
