  • Patent number: 5820788
    Abstract: The present invention relates to antistatic polymers containing a mixture of a thermoplastic resin and about 8-20% by weight of conductive partially carbonized chopped linear carbonaceous fibers. The chopped carbonaceous fibers have a carbon content of about 70-85% by weight and an electrical resistivity of about 10.sup.-2-10.sup.3 ohm-cm. The composite has a surface resistivity of about 10.sup.4 -10.sup.10 ohms/square. These intermediate surface resistivities make the composite an excellent choice for use with plastic parts that come into direct contact with electronic components and circuitry.
