UNIGARD™ HP DFDA-6530 NT Datasheet,PE Copolymer,The Dow Chemical Company-SHANGHAI SUSHENG

Message
UNIGARD™HP DFDA-6530 NT is a flame retardant, irradiated cross-linked polyethylene copolymer used as wire insulation material. It is recommended to use it for 600 volt power cables and control cables, which are suitable for applications with operating temperatures as high as 90°C in humid environments. UNIGARD™HP DFDA-6530 NT can be used in XHHW, RHW, RHH, SIS, and USE A, B or C applications. When the insulation layer thickness is 30 mil (0.76mm), its 14 AWG wires can meet the VW-1 application requirements. This material has been approved for UL Style 20292 applications. Each manufacturer must contact UL for certification requirements related to the purpose of its application. The best performance can be obtained when the irradiation amount is 20 megarads.

Extrusion instructions
Conditions for a commercial extrusion run using DFDA-6530 NT are shown below. Using these conditions with a standard polyethylene screw afforded high quality finished wire. Exact extrusion characteristics will, of course, be dependent on the equipment in use and can only be determined during cable trials. Hopper drying at 150°F (66°C) before extrusion is recommended to remove moisture and diminish the possibility of die drool. Drying time is 4-6 hours.Compound DFDA-6530 NT on #14 Solid Copper Conductor with 0.030" (0.76 mm) Wall Thickness. Extruder Screw L/D: 15:1 to 20:1 Screw Suggested: Single Flight Compression Ratio: 2.5:1 to 3.5:1 Screen Pack: 40/20 mesh Extrusion Temperatures Typical conditions for 2.5 in diameter 24:1 L/D extruder Barrel Feed Zone: 255°F (124°C) Barrel Center Zone: 255°F (124°C) Barrel Metering Zone: 260°F (127°C) Crosshead: Head: 255°F (124°C) Die: 250°F (121°C) Melt Temperature: 265°F (129°C) Screw: Circulating Water: 170°F (77°C) Coloring UNIGARD™ HP DFDA-6530 NT is a colorable compound. Our experience has been that the color masterbatch materials recommended for use with polyethylene wire and cable products serve the purpose in the DFDA-6530 NT. Generally speaking, color masterbatch added at the two percent by weight level gives adequate color and disperses well in the extrusion process.
