SI-LINK™ Crosslinkable Polyethylene DFDA-5451 NT is an ethylene-silane copolymer developed for use in power cable and control cable applications up to 1 kV.
DFDA-5451 NT may be crosslinked after it is extruded with the DFDB-5480 NT catalyst masterbatch by exposing it to moisture after cable manufacture. If a black product is required for UV protection, the addition of DFDB-5410 BK carbon black masterbatch is recommended.
Because the catalyst and carbon black masterbatches are shipped separate from the DFDA-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.
Specifications
When DFDA-5451 NT is crosslinked with DFDB-5480 NT, and optionally, DFDB-5410 BK, it meets typical 1 kV or less low voltage specifications such as those in:
UL 854
ICEA: S-66-524
CSA RW90
IEC: 60502-1
