Antistatic PETGs Aim at Thermoforming.Three new antistatic grades of Eastar PETG PETG Polyethylene Terephthalate Glycol PETG Performance Evaluation Task Group 6763 packaging resin have been introduced by Eastman Chemical Co., Kingsport, Tenn. These EastaStat grades are aimed at sheet extrusion and thermoforming of electrical/electronics specialty packaging. EastaStat PETG GSP GSP Good Scientific Practice GSP Generalized System of Preferences GSP Gross State Product GSP German Shorthaired Pointer (dog breed) GSP Geometer's Sketchpad (KTP Technologies geometry software) GSP Georges St. 11, an alloy with a proprietary copolymer copolymer: see polymer. , is a washable, inherently static-dissipative resin with low outgassing Outgassing (sometimes called "Offgassing," particularly when in reference to indoor air quality) is the slow release of a gas that was trapped, frozen, absorbed or adsorbed in some material. . It was developed for packaging hard-disk-drive components. Its surface resistivity is [10.sup.10] ohm/sq at 50% RH and [10.sup.11] ohm/sq at 12% RH. EastaStat PETG GSP21 is a clear, antistatic PETG for one-way electronic packaging of computer/electronic parts. Surface resistivity is [10.sup.9] ohm/sq at 50% RH and [10.sup.10] ohm/sq at 12% RH. EastaStat PETG GSP31 is a conductive, toughened compound containing carbon black. Its surface resistivity is [10.sup.4] ohm/sq at any RH. |
