Premix Thermoplastics PRE-ELEC® ESD 7140 Static Dissipative Thermoplastic Compound
Categories:	Polymer; Thermoplastic; ABS Polymer; Acrylonitrile Butadiene Styrene (ABS), Molded
Material Notes:	PRE-ELEC® ESD 7140 is a static dissipative thermoplastic masterbatch based on ABS. The dissipative property is permanent and built into the polymer chain. PRE-ELEC® ESD 7140 has been developed for injection moulding. The products made out of PRE-ELEC® ESD 7140 are washable, reusable and recyclable. Surface resistance values of 10⁸ ohms (IEC 61340-5-1, EOS/ESD S11.11-1993) can be achieved with optimum processing parameters. Applications: Trays, tote bins, crates and technical parts which give permanent ESD protection for the electronics, medical, pharmaceutical and paper handling industries. PRE-ELEC® ESD 7140 can be coloured into various bright colours. Test Specimen: 10[mm] wide moulded rod Information from Premix OY
