What is SI-LINK™ AC DFDA-5488 NT Moisture-Curable Compound?
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 this product is mixed with DFDB-5451 NT, the resulting system has excellent scorch resistance during extrusion. This product 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 the product 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.
