LG Chemical LUCON CP-4208F Conductive Thermoplastic, Flame Retardant  (discontinued **)
Categories: Polymer; Thermoplastic

Material Notes: LG Chemicals has formulated a diverse range of LUCON thermoplastic compounds containing conductive additives, such as carbon powder, (nickel coated) carbon fiber, or stainless steel fiber for solving problems associated with build-up of electrostatic charges, electrostatic discharge, and electromagnetic interference. These materials span the surface resistivity spectrum from antistatic through conductive to EMI shielding (100-1012O).

Applications: I.C. tray, wafer carrier, I.C. magazine, notebook PC case, home appliance part, LCD cassette tray
