  • Carbon-phenol resin molding compound
    Patent number: 7199186
    Abstract: A carbon-phenol resin molding compound is provided, which is preferably used to obtain molded articles having high electrical and thermal conductivities as well as good mechanical strength. The resin molding compound is prepared by reacting a phenol with an aldehyde in the presence of a catalyst, while mixing them with a carbon powder such that a content of the carbon powder in the molding compound is 75 wt % or more. The catalyst is at least one selected from tertiary amines, carbonates, hydroxides and oxides of alkali metals or alkali earth metals.

  • Electromagnetic wave shielding material
    Patent number: 5310784
    Abstract: An electromagnetic wave shielding material comprises a composite carbon-resin compound obtained by reacting to proceed polymerization of a resin forming material with carbon powder intermixed therewith. The resulting compound has carbon powder substantially uniformly dispersed in the resin and exhibit superior electromagnetic wave shielding effect, in addition to good fire resistance. The resin may be phenol, melamine, furan or the like, and the carbon powder is preferred to be incorporated at a content of not less than 40% of the total weight.
