Low density moisture curable polyethylene compound for low voltage building wire, control cable and cable tray applications (UL styles SIS, XHH, XHHW, XHHW-2, RHH, RHW, and RHW-2 VW-1) Pexidan® V/T 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-010FR. Mixed and extruded in the proper proportions (50/50), the two components result in a material that is curable by exposure to hot water. Pexidan® V/T is a RoHS-compliant system. |

| Curing can be done in the following ways: by immersion in hot water at 70-90°C by exposure to low pressure steam 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) are obtained from a 14 AWG wire with 30-mil wall thickness, cured in hot water (6 hours @ 95°C). |
