Material Notes:
PRE-ELEC ESD 7120 is a static dissipative thermoplastic compound based on ABS. The dissipative property is permanent and built into the polymer chain. PRE-ELEC ESD 7120 has been developed for injection molding and for the extrusion of thermoformable mono- or multi-layer sheet. The products made out of PRE-ELEC ESD 7120 are transparent, 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 trays, tote bins, crates and technical parts which give permanent ESD protection for the electronics, medical, pharmaceutical and paper handling industries. PRE-ELEC ESD 7120 can also be used as covers and lids as it is transparent.Information provided by Premix Thermoplastics Inc.
