Chemically crosslinkable high density polyethylene for injection moulding The SX739 system is a silane grafted HDPE compound curable by exposure to moist conditions. It is specifically designed for high output processing by conventional thermoplastic injection moulding equipment. The graft component SX739 is mixed with a crosslinking catalyst masterbatch CM488-6 generally in the ratio 95:5. This material combines good flow, high rigidity and excellent notched impact strength. The two component system SX739:CM488-6 has high degree of crosslinking which gives it a useful strength at temperatures not usually reached by HDPE. |

| By conventional thermoplastic injection moulding equipment using temperatures set in the range 200°C - 250°C. It is essential to minimise moulding stresses since these may be released during elevated temperature cure or service, causing warpage. |
