SX744:CM488

Technical Datasheet | Supplied by AEI Compounds

SX734:CM488 by AEI Compounds is a silane crosslinkable medium density polyethylene (MDPE) grade. Exhibits excellent impact strength, environmental stress cracking resistance (ESCR), creep and internal pressure resistance under ambient and elevated temperature conditions. The graft component SX744 is mixed with a crosslinking catalyst masterbatch CM488 generally in the ratio 95:5. Offers good extrusion properties at high output rates and is curable by exposure to moist conditions. SX734:CM488 is used in high temperature pressure pipes (both hot and cold water pipes). Pipe produced from SX734:CM488 meets the internal pressure requirements of DIN 16892.
