SACO AEI PEXIDAN® R/T Curable Polyethylene Compound
Categories:	Polymer; Thermoplastic; Polyethylene (PE)
Material Notes:	Description: PEXIDAN® R/T is a low density XLPE system curable by moisture and consists of a silane pre-grafted base compound A-3001 and a catalyst masterbatch CAT-009. Mixed in the proper proportions (95/5) the two components result in a material that is curable by exposure to 70-95°C hot water or even ambient moisture. PEXIDAN® R/T is listed with the Canadian Standards Association for use in RW-90 and RWU-90 XLPE applications and rated to -40ºC. PEXIDAN® R/T is non-flame-retardant, halogen-free and RoHS-compliant.
