abstract |
The present invention provides a permanently antistatic, injection moldable thermoplastic composition comprising a polybutylene terephthalate resin having an intrinsic viscosity in the range of about 0.7 to about 1.4 deciliters per gram measured in ortho-chlorophenol at 25 DEG C., an antistatic dopant comprising an electron acceptor compound, an electron donor compound, and polytetrafluoroethlene, and less than about 10 percent by weight based on the total weight of the molding composition of carbon fibers having lengths between about 0.1 and about 1.0 inch. Such a molding composition exhibits a volume resistivity of less than 1x108 ohm-cm, exceptional low wear performance, excellent mechanical properties, and ease of manufacture. |
