Product Description
UNIGARD™ HP DFDA-6530 NT is a flame retardant, irradiation crosslinkable, polyethylene copolymer wire insulation material. It is recommended for use in 600 volt power cable and control cable applications and is suitable for 90°C service in
wet locations.

UNIGARD™ HP DFDA-6530 NT is formulated for use in XHHW, RHW, RHH, SIS, and USE A, B or C applications and is VW-1 on 14 AWG wire with a 30 mil (0.76 mm) insulation wall thickness. This compound has been approved for constructions for UL Style 20292. Each manufacturer must contact UL regarding approval requirements for the intended application. Optimum performance is obtained at an irradiation dosage level of 20 megarads.

Extrusion Notes
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.

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.
