Technical Information Original Material "S" plus+® white ESD Production based on PE-UHMW TG 1.2 Technical properties Material colour Average molecular weight Sheet group Density Water absorption – saturation at 23 °C Mechanical properties 1) Yield stress Breaking elongation Coefficient of elasticity (tensile test) Charpy impact strength – two-sided notch Shore hardness D Indentation hardness Sand-Slurry-Test Average coefficient of friction against steel 6) Legend The material characteristic tables, which are based on data from our suppliers of raw materials, are intended to help you to quickly compare/select a material. The values stated are short-term values that can be affected by processing, environmental, and application conditions. The user is solely responsible for the suitability of the selected material for the specific application. RH Relative humidity NB no break 1) The mechanical and electrical characteristics are based on a test in standard atmosphere at 23 °C/ 50% relative humidity (RH). Temperature stress for several hours; no or low mechanical stress (short-term service temperature). Maximum continuous operating (0,25 m/s, 0,25 N/mm2) Average coefficient of friction against POM 6) (0,25 m/s, 0,25 N/mm2) Thermal properties Heat conductivity at 23 °C Linear thermal coefficient of expansion α: (Average value between 23 and 60 °C) Upper service temperature short-term in air 2) Upper service temperature constant in air (5000h) 3) Lower service temperature 4) Burning behavior UL 94 – sample thickness 3/6mm Melting temperature The electric strength can be up to 50% lower than for natural colored materials (for black materials Murylon®, Murylon®, Murytal®, Murylat®, Murpec®). As the temperature decreases, the impact strength drops. The specified values are based on the most unfavourable impact load possible and do not represent absolute practical limits (lower service temperature). Electrical properties 1) Electric strength Specific contact resistance Specific surface resistance temperature in air: the specified temperature limit is based on the thermo-oxidative degradation (“aging”) after the specified period. It does not refer to the mechanical strength of the material. Test period 24 h, oscillating measurement method.
