| Moisture-curable Low Smoke Zero-Halogen (LSZH) insulation compound for low voltage building wire applications (UL styles XHHW-2, RHW-2, RHH, SIS). PEXIDAN ® HF X/T is a unique low smoke halogen-free flame retardant 90°C wet-rated XL-insulation system curable by moisture. It consists of a silane pre-grafted base compound SX-0651 and a catalyst masterbatch CM540U or CM540U/1. Mixed and extruded in the proper proportions (95:5), the two components result in a material that is crosslinkable by exposure to 90°C hot water. PEXIDAN ® HF X/T is REACH and RoHS-compliant and is UL 2885 certified to bear the Halogen Free “HF” designation. PEXIDAN ® HF X/T is UL-bulletinized and wire made with this insulation system may be marked as Oil Resistant “PR I” and “PR II”, Gas & Oil Resistant “GR I” and “GR II”, and “-40C”. This compound will meet 105°C dry rating.&& |
