SI-LINK™ DFDB-5400 NT is a RoHS (Reduction of Hazardous Substances)-compliant flame retardant masterbatch designed to be used in conjunction with SI-LINK™ DFDA-5451 NT Polyethylene and the catalyst masterbatch SI-LINK™ DFDB-5480 NT Polyethylene to form a flame retardant SI-LINK polyethylene insulation system. This system is bulletinized by UL as DFDB-5425 and is moisture curable. The specific gravity of the system is 1.04. It is recommended for use in low voltage power cable and industrial cable applications. SI-LINK™ DFDB-5400 NT is formulated to pass the UL-44 horizontal burn test on 14 AWG (1.63 mm) wire, 0.030 in. insulation wall thickness, at a 25% loading with 70% SI-LINK™ DFDA-5451 NT and 5% SI-LINK™ DFDB-5480 NT.

UV resistance allowing the wire to be printed "SunRes" may be achieved with the addition of a UV stabilizer package. The formulation for such an additive is available upon request and the resulting product is bulletinized by UL as DFDB-5425 UV. For accelerated curing applications SI-LINK™ DFDB-5400 NT can be used in conjunction with SI-LINK™ AC DFDB-5451 NT Polyethylene and the catalyst masterbatch SI-LINK™ AC DFDA-5488 NT Polyethylene to form a flame retardant SI-LINK™ AC polyethylene insulation system. This system is recognized by UL as DFDB-5425 AC. It is formulated to pass the UL-44 horizontal burn test on 14 AWG (1.63 mm) wire, 0.030" wall thickness, at a 25% loading with 70% SI-LINK™ DFDB-5451 NT and 5% SI-LINK™ AC DFDA-5488 NT.
