The paper presents the results of tests aimed at checking suitability and applicability of materials in the group of multiblock thermoplastc elastomers for electrotechnical purposes. The modifications in chemical composition of the materials concerned allow to influence their mechanical and electric properties, and thus better material suitability for particular uses. Special structure of the polymers considered provides more advantageous improvements in properties than the addition of fillers to polymers. There were main electric parameters tested for the series of terpoly(ester-b-ether-b-amide) - (PBT-b-PTMO-b-PA12.10)-n , i.e. resistivity, dielectric loss coefficient, resistance to electric arc and tracking resistance, as well as the changes in the above parameters in conditions of long-lasting moist exposure. The results obtained confirmed the suitability of tested materials for electrotechnical purposes.
