FIBRIL nanotubes can be used at low loadings in all the polymers typically used to make static dissipative test sockets. The nanotube filled polymers provide the necessary static decay, while maintaining a relatively high surface resistivity. In contrast, other static decay materials become too conductive and compromise the device’s signal integrity with cross-talk between contacts. ?In addition to special electrical characteristics, the low loading of FIBRIL nanotubes also preserves more of the base resin’s toughness compared to traditional conductive additives.?
