Product Description
DFDA-5488 NT is a fast cross-linking catalyst masterbatch designed to be used with the scorch retardant DFDB-5451NT ethylene-silane copolymer in order to produce insulation for power and control tray cables up to 1KV.

Because the catalyst masterbatch is shipped separately from the silane-modified polyethylene, the components are very shelf-stable. Crosslinking of the insulation system only occurs after hot melt mixing of the two components and exposure to moisture. When DFDA-5488 NT is mixed with DFDB-5451 NT, the resulting system has excellent scorch resistance during extrusion.

DFDA-5488 NT includes sufficient antioxidant so that the SI-LINK™ AC system provides excellent processing and product performance. This insulation system is designed to be effective on either copper or aluminum conductors.

The recommended level of usage for DFDA-5488 NT is 5% by weight. The specific level will depend on the process and conditions used. For your particular application, contact your Dow representative for recommended levels.
