We have been working on a similar process. 3Dimensional Engineering is
authorized to distribute a patented injection mold thermoplastic that has
20% - 25% better thermal conductivity of aluminium at 1/10th the weight.

This material was developed as an alternative for heat pump elements
to eliminate corrosion during operation.
