Abstract: The present invention relates to a polybutylene terephthalate composition, comprising (A) 40 to 99.8% by weight of polybutylene terephthalate, (B) 0.2 to 10% by weight of at least one conductive filler selected from the group consisting of carbon nanotubes, carbon nanostructures, and a combination thereof, and (C) 0 to 50% by weight of glass fiber, each being based on the total weight of the poly butylene terephthalate composition, wherein the carbon nanostructures each comprise a plurality of carbon nanotubes which are branched, crosslinked, and/or sharing common walls with one another. The present invention also relates to an EMI shielding article produced from the polybutylene terephthalate composition.

Abstract: The present invention relates to a polybutylene terephthalate composition, comprising (A) 45 to 75% by weight of polybutylene terephthalate, (B) 20 to 45% by weight of at least one carbon fiber, (C) 0 to 20% by weight of at least one solid filler other than the carbon fiber (B), and (D) 0 to 30% by weight of at least one thermoplastic polyester other than polybutylene terephthalate, each being based on the total weight of the polybutylene terephthalate composition, wherein the at least one carbon fiber has a carbon content of 93% by weight or greater, and comprises a sizing agent other than epoxy sizing agent. The present invention also relates to an EMI shielding article produced from the polybutylene terephthalate composition.
