路博潤ESTANE ZHF 78AT3 TPU Technical Data Sheet TYPE: Estane? ZHF 78AT3 is a Soft, Polyether based, NHFR Thermoplastic Polyurethane (TPU) Compound Description: Non-Halogenated flame retardant compound Uses: Wire and cable and general extrusion where flame retardant properties are required ? Prior to testing samples were conditioned at 23°C for 48 hours. ? Physical Property test is based on 2mm molded plaques. Listed data above is a “typical data”, and should/cannot be applied for specification pure Materials Preparation: Prior to process, Estane ZHF 78AT3 must be dried under 105o C for 3 hours. It is recommended drying this materials in a dehumidifier, target dew point to be -30o C, preferable – 40o C Depending on the process technique, the maximum moisture content is recommended <0.02%. Process Condition: Estane ZHF 78AT3 is extruded on any conventional extruder equipped with a PVC, 3 stage or barrier type screw hing an L/D ration of 25:1 and a compression ratio of 3:1 See reverse side for processing information.
