SX720:CM488

SX559:CM540U by AEI Compounds is a silane crosslinkable polyethylene (XLPE) grade. Exhibits excellent impact strength, environmental stress cracking resistance (ESCR), creep and internal pressure resistance under ambient and elevated temperature conditions. The graft component SX720 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. SX559:CM540U is used in high temperature pressure pipes (both hot and cold water pipes). Is approved as suitable for use in contact with potable water up to 85°C and listed with Water Regulatory Advisory Scheme (WRAS), DVGW and NSF 61. Pipe produced from SX720:CM488 meets the internal pressure requirements of DIN 16892, BS 7291 Class S and NSF 14.
