Chemically crosslinkable, high density polyethylene for injection molding

Material SX739 is a silane grafted HDPE compound curable by exposure to moist conditions. SX739 is specifically designed for high output processing by conventional thermoplastic injection moulding. 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.

These materials have been formulated for hot and cold water pressure pipes and are easily extrudable on conventional polyethylene extrusion lines.
