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. SPECIFICATIONS The DFDB-5425 systems are bulletinized by UL for XHH, XHHW, XHHW-2, RHH, RHW, RHW-2, SIS, USE and USE-2. They are also suitable for CSA RW-90, and RWU-90 applications. |

| The data below summarizes conditions for a commercial extrusion run of DFDB-5425 (DFDB-5400 NT /DFDA-5451/DFDB-5480, 25%/70%/5%). Using these conditions with a standard polyethylene screw afforded high quality finished wire.Desiccant drying of the masterbatches at 150°F (66°C) for 4-6 hours is recommended. Wire pre-heat of 176-212°F (80-100°C) is recommended to obtain the typical physical properties for circuit size conductors. Adequate curing requires exposure for a minimum of 24-48 hours to 194°F (90°C) water or steam. Exact extrusion characteristics will of course be dependent on the equipment in use and can only be determined during cable trials.ExtruderScrew L/D: 15:1 to 20:1Screw Suggested: Single FlightCompression Ratio: 2.5:1 to 3.5:1Screen Pack: 20/40/60/20 Mesh |
