These materials are formulated using select engineering resins along with proprietary conductive additives, and have been shown to improve thermal conductivity by 50-100 times that of conventional plastics. 

In addition, the formulations process with similar shrink to nylons, set up quickly, and have short cycle times.

Similar to other resin systems, the addition of a color pigment may lower mechanical properties.
