Low density moisture curable polyethylene compound for low voltage underground service entrance cables (UL styles USE and USE-2). Pexidan® U/T is a low density XLPE system curable by moisture and consists of a silane pre-grafted base compound A-3001 and a catalyst masterbatch CAT-008. When mixed and extruded in the proper proportions (95/5), the two components result in a material curable by exposure to 70-90°C hot water or even ambient moisture. In order to prevent pre-scorching the grafted compound and the catalyst masterbatch must be stored separately and mixed only when used. Pexidan® U/T is RoHS-compliant. |

| 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 (except MFR and Weather-o-meter) are obtained from 14 AWG samples with 30-mil wall thickness, cured in hot water (6 hours @ 95°C). Weather-o-meter testing was performed on 7 stranded, 6 AWG sample. |
