  • Patent number: 8747003
    Abstract: A pencil that includes a polymer-bonded lead, a polymerbonded wood substitute material that includes an organic filler and covers or surrounds the lead along its length, and an adhesion promoter layer disposed between the lead and the wood substitute material. The lead and the wood substitute material each have a polymer. The polymer in the lead being incompatible with the polymer in the wood substitute material so that the polymer of the lead and the polymer of the wood substitute material do not create any connection with one another. The adhesion promoter layer is connected to the polymer in the lead and to the polymer in the wood substitute material so that the adhesion promoter layer forms a connection with the polymer in the lead and with the polymer of the substitute material. The organic filler is formed by particles having a maximum particle size of 250 ?m.
