Premix Thermoplastics Inc. has introduced electrically conductive thermoplastic compounds with controlled resistance levels.
Pre-Elec CR compounds allow the user to choose a volume or surface resistivity range. The Milton, Wis., company carefully controls conductive additive levels to achieve the range. The compounds can, in many cases, substitute for more costly, inherently dissipative polymers to provide static dissipation, Premix claims.
Depending on the polymer and resistance range, Premix uses carbon black, inherently conductive polymer alloys or inherently dissipative polymers to tune the resistance range.
