Premix Thermoplastics PRE-ELEC® ESD 7200  (Unverified Data**)
Categories: Polymer; Thermoplastic; ABS Polymer; Polycarbonate (PC)

Material Notes: PRE-ELEC ESD 7200 is a static dissipative thermoplastic compound based on PC/ABS. The dissipative property is permanent and built into the polymer chain. PRE-ELEC ESD 7200 has been developed for injection molding. The products made out of PRE-ELEC ESD 7200 are washable, reusable and recyclable. Surface resistance values of 108 ohms (EOS/ESD S11.11-1993, IEC 61340-5-1) can be achieved with optimum processing parameters.

Typical applications include injection molded technical parts used in e.g. office machines, telecommunication, electronics, medical and pharmaceutical industries, which give permanent ESD protection. PRE-ELEC ESD 7200 can also be extruded into sheets for thermoforming.
