Low density moisture curable polyethylene for low voltage building wire applications (UL styles XHHW-2, RHW-2, RHH, SIS, USE-2 - UL ‘Sunlight Resistant') Pexidan® X/T-UV is a low density XLPE system curable by moisture and consists of a silane pre-grafted base compound A-3001 and a flame-retardant catalyst masterbatch CAT-005FRUV1. Mixed and extruded in the proper proportions (80:20), the two components result in a material that is curable by exposure to 70-90°C hot water or even ambient moisture. Pexidan® X/T-UV is a RoHS-compliant system. Insulation made with this system may be marked SUNRES in all colors for sizes of 6 AWG and larger per UL44. |

| Curing can be done in the following ways: by immersion in hot water at 70-90°C by exposure to low pressure steam ambient atmospheric moisture In all cases curing time depends on wall thickness, temperature, relative humidity and quantity of wire on the reel.Typical values reported above are obtained from 14 AWG samples with 30-mil wall thickness, cured in hot water (6 hours @ 95°C). Weatherometer testing performed on stranded 6 AWG sample. Oxygen Index performed on a 4mm thick compression-molded sample. |
