                A chemically cross-linkable HDPE compound for production of single / multi-layers /composite pipes for domestic hot and cold water, under floor heating and central heating application.

                Description 
                TA1122HD is a cross-linkable compound made by silane grafted ethylene polymer according to 2 step or SIOLPLAS process. This graft polymer constitutes together with a masterbatch containing the cross-linking catalyst and stabilizer. Pipe produced with TA1122HD fulfils the 165h, 1000h, 8760h static pressure test by National Test Center of Polymer And Chemical Building Materials. Sanitary safety data is approved 《Standard for safety evaluation of equipment and protective materials in drinking water system》(GB/T 17219-1998) by Institute of Environmental Health Monitoring, Chinese Academy of Preventive Medicine.
                TA1122HD can be extruded as a normal thermoplastic polymer. Once touching with moisture, the cross-linking reaction will be started. Already mixed graft and catalyst has to be fabricated during 2 hours.

                Typical Physical Properties



                Proportions
                Please note that the level of catalyst masterbatch should not be reduced below 5%. If color masterbatch or process aid is added, the content of graft polymer should be reduced accordingly. In general, all types of masterbatch should be dried before extrusion.

                Extruder
                TA1122HD can be processed on most modern thermoplastic extruders without problem. Particularly if the available screw is designed for high density polyethylene, excellent products can be expected.Screw Parameters:Length-to-diameter(L/D) ratio >25 Compression ratio 3-2.5:1 

                Typical Temperature Profile (Reference only)



                Suggestion for best extrusion
                Pre-dry the catalyst masterbatch and color masterbatch at a temperature of 80-90℃ for 2 hours.
                Reasonable design of head and die to obtain a streamline production.
                When the machine is restarted after stopping more than 10-15min, it should be purged by HDPE(MFI,190℃/2.16kg:0.3g/min).
                Material with broken bags should not be used.

                Cross-linking
                Cross-linking method is immersion in hot water or exposure to low pressure steam. The period required to obtain the final gel content depends on the thickness, concentration of catalyst and temperature.

                Storage
                The storage life is nine months if TA1122HD can be stored in a suitable condition.
                he package is opened only shortly before processing.
                The product has to be stored in a cool and dry place.
                       
                Packing
                Graft polymer: Aluminium-plastics bags containing 25kg or 600kg, sealed under vacuum.
