Material Notes:
PRE-ELEC® ESD 6020 is a dissipative masterbatch developed for coextruded HIPS-sheets. The active substance is an IDP (inherently dissipative polymer) and it gives a permanent static dissipative property also at low humidity. The surface resistance level of 109-1010 ohms can be achieved at 20-25 % dosing level (EOS/ESD S11.11-1993, IEC 61340-5-1). The let down ratio of the masterbatch with high impact polystyrene should be tested prior to its use with the polymer used in order to reach the desired dissipative level. The thickness of the outer layers can be thin (< 5%) depending on the extrusion line. With good processing the adhesion between the outer dissipative layer and the core layer is excellent. PRE-ELEC® ESD 6020 provides a cost-effective solution for protecting the fragile electronics components. Because of the ion content, the material may not be accepted in all clean room applications. The processing temperature should be less than 220°C (430ºF) and the material should be pre-dried before processing. The performace of ESD 6020 in coextrustion can further be improved by adding ~5% of SBS. This improves the ductility of the outer layer and the adnesion between the layers.Processing: PRE-ELEC® ESD 6020 should be diluted with extrusion grade high-impact polystyrene. PRE-ELEC® ESD 6020 / HIPS dry blend can be processed in normal processing conditions as with polystyrene.Information from Premix OY
