| SI-LINK™ AC Crosslinkable Polyethylene DFDB-5451 NT is a scorch retardant ethylene- silane-copolymer developed for use in power cable and control cable applications up to 1 kV. DFDB-5451 NT may be crosslinked under ambient conditions after it is extruded with the DFDA-5488 NT catalyst masterbatch. If a black product is required for UV protection, the addition of DFDB-5410 BK is recommended. Because the catalyst and carbon black masterbatches are shipped separately from the DFDB-5451 NT copolymer, the components are very shelf-stable. Crosslinking of the total system only occurs after hot melt mixing of the components and exposure to moisture and temperature. Specifications When DFDB-5451 NT is crosslinked with DFDA-5488 NT, and optionally, DFDB-5410 BK, it should meet typical 1 kV or less low voltage specifications such as those in: UL: 854 ICEA: S-66-524 CSA: RW90 IEC: 60502-1&& |
