SACO AEI PEXIDAN® V/T Curable Polyethylene System
Categories:	Polymer; Thermoplastic; Polyethylene (PE)
Material Notes:	Description: PEXIDAN® V/T is a low density flame-retardant XLPE system curable by moisture and consists of a silane grafted base compound A-3001 and a flame-retardant catalyst masterbatch CAT-010FR. Mixed and extruded in the proper proportions (50/50), the two components result in a material that is curable by exposure to hot water. PEXIDAN® V/T is halogenated but is RoHS-compliant. Information provided by SACO AEI Polymers.
