- Polyethylene Cross-Linked (PEX)PolyethylenesPolyolefins
TABOREX® TA 1108 HD is a crosslinkable compound made by Silane grafted ethylene polymer. This graft polymer constitutes together with a TABOREX® Masterbatch containing the crosslinking catalyst a “SIOPLAS-SYSTEM”. Pipes which are produced with the SILON grade TABOREX® TA 1108 HD fulfill the requirements of ASTM F876, CSA 137.5, EN ISO 15875, BS 7291, NSF/ANSI 14, NSF/ANSI 61 and all related standards. This system allows the compound to be extruded as a normal thermoplastic polymer and will attain a high level of crosslinking in the processed form. The final product provides all the superior properties associated with crosslinked polyethylene.

- Storage and Handling
TABOREX TA 1108 HD has a shelf life of nine months from the production date printed on the packaging. The packages should be stored in dry conditions at ambient temperature below 30 °C and protected from UV light. The packages should be opened only before processing and after opening of the inliner the product must be used within 3–4 hours.
- Processing Guidelines
- 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.
