ABSTRACT:
The present invention provides a short-fiber containing composition inhibited from electrostatic charging and having practical insulating properties. This composition has a volume resistivity of 10.sup.5 -10.sup.13 .OMEGA.cm and comprises 10-40 parts by weight of at least one kind of short fibers having a volume resistivity of 10.sup.-1 -10.sup.3 .OMEGA.cm and 90-60 parts by weight of a polymer or comprises 10-40 parts by weight of a mixture comprising at least one kind of short fibers having a volume resistivity of less than 10.sup.-1 .OMEGA.cm and at least one kind of short fibers having a volume resistivity of 10.sup.-1 .OMEGA.cm or more and 90-60 parts by weight of a polymer. A method for controlling the polymer composition to 10.sup.5 -10.sup.13 .OMEGA.cm in volume resistivity is also provided.
