摘要： A conductive composition is obtained by dispersing conductive particles in a curable polymer. At least 50% by weight of the entire conductive particles are those conductive particles coated with a metal on their outermost layer surface and having a specific gravity which differs within ±1.5 from the specific gravity of the curable polymer. The composition remains stable during storage, experiences a minimal change with time of curability, and cures into a conductive rubber which experiences a minimal change with time of volume resistivity.

摘要： Carbon fiber-filled PC-ABS resin compositions which have improved electrical properties at a given level of carbon fibers, and which do not suffer from as significant a decrease in impact strength as would result from the introduction of generic carbon fibers are achieved using carbon fibers treated with a polyamide terpolymer binder. The bundles are dispersed within the PC-ABS blend. The compositions can be used for injection molding of articles for use as components in applications requiring static dissipation and/or EMI shielding. Such articles include, but are not limited to electronic devices, dust handling equipment and notebook computer enclosures.

摘要： A conductive thermoplastic composition is prepared by a method in which poly (arylene ether) and, optionally, a portion of polyamide are added to a first feed port, polyamide is added to a second feed port, and a concentrate of conductive carbon black in polyamide is added to the second feed port or a third feed port. Whereas preparation of conductive poly(arylene ether)/polyamide compositions has typically required an extruder having at a screw length to diameter ratio of at least 40, the present method allows the use of extruders having a screw length to diameter ratio less than 38 and as low as 20 or lower. The conductive thermoplastic composition prepared by the method exhibits high conductivity and high impact strength, and it is useful for molding articles such as electrostatically-paintable automotive exterior panels.

摘要： Carbon fiber-filled, thermoplastic resin compositions having improved electrical properties at a given level of carbon fibers are formed from thermoplastic resin and carbon fibers associated into bundles with a binder. The thermoplastic resin and the binder are selected to be incompatible such that the adhesion of the fiber to the resin is poor. An exemplary composition is formed from a thermoplastic polymer selected from among polystyrene, high impact polystyrene, polycarbonate, polybutylene terephthalate, polyethylene terephthalate, polyphenylene ether, polyether imide and blends thereof; and carbon fibers associated into bundles with a polyamide terpolymer binder. The bundles are dispersed within the thermoplastic polymer. The compositions can be used for injection molding of articles for use as components in applications requiring static dissipation and/or EMI shielding. Such articles include electronic devices, dust handling equipment and notebook computer enclosures.
