Message
Control cable insulation UNIGARD™HP HFDA-1544 Natural is a flame-retardant, peroxide-cured polyethylene copolymer used as a wire insulation material. It is recommended to apply it to 600 volt power cables and control cables. It is suitable for wet and dry occasions such as UL XHHW-2 or Canadian Standards Association (CSA) RW-90 at an operating temperature of 90°C. When this product was developed, it was considered to widen its processing temperature window to reduce the scorch phenomenon in the extrusion system that can cause problems, and reduce odor and head drop due to the use of peroxide curing system. Specifications HFDA-1544 Natural have been UL announced to meet the requirements of XHHW, XHHW-2, RHH, RHW, RHW-2, SIS, USE, USE-2 and VW-1 applications. The material is also applicable to applications specified by the Canadian Standards Association NMD-90 and RW-90.

Extrusion instructions
The Extrusion Profile summarizes conditions for a commercial extrusion run on UNIGARD-HP HFDA-1544 Natural. Using these conditions with a standard polyethylene screw afforded high quality finished wire meeting the specifications set forth in Underwriters Laboratories, Subject 44 (XHHW, SIS, USE, A, B or C applications and VW-1). 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 (65°C) before extrusion is recommended to remove moisture and diminish the possibility of die drool.Extrusion Profile Compound: HFDA-1544 on #14 7/STR (1.84 mm) Bare Copper, .030 in, 3 1/2 in Extruder Head: 235°F (113°C) Die: 180°F (82°C) Zones: RF 235, 235, 235, 240, 250°F (113, 113, 113, 115,121°C) Screw: 180°F (82°C) Stock: 250°F (121°C) Speed: Dependent on steam leg length. Allow for residence time of approximately 1 min. for 14 AWG (1.63 mm dia.) and 0.030 in. wall.
