Extruder: TABOREX TA 1108 HD can be processed on standard thermoplastic extruders without problems. Particularly if the available screw is designed for polyethylene excellent products can be expected. Screw parametres: L/D: > 25 Compression ratio: 2,5–3 : 1 Temperature profile: Zone 1: 160–170 °C Zone 2: 170–180 °C Zone 3: 170–190 °C Zone 4: 170–190 °C Head 200–210 °C Die 190–220 °C Screw* 70–90 °C *The thermostatic control of the screw improves processing results Recommendation for optimal extrusion conditions: • Pre-drying of foreign masterbatches e.g. color, PPA and others. Drying has to be done preferably with dried air. Residual moisture of the added masterbatches must not exceed 0,02 %. • Material preconditioning to ambient temperature before the package opening is necessary, to avoid moisture condensation on the pellet surface. • Use screw suitable for PE-HD (3-zone or barrier screw). • Head and tools should be designed allowing streamlined flow avoiding stagnation of the material. • In case of line stop longer than 10–15 minutes: Before restarting purge with standard HDPE (MFI: 0,3 g/10 min.)
Crosslinking Cure:
The following methods are recommended: • Autoclave using saturated steam at 100–115 °C (optimal methode) • By immersion in hot water at 80–95 °C • Exposure to low pressure steam The period required to obtain the final gel content depends on the wall thickness and the temperature. The exposure times are in the range of 4–8 hours.
