Message
SI-LINK™Cross-linked polyethylene DFDA-5451 NT is an ethylene-silane copolymer used for power cables and control cables below 1 kV. DFDA-5451 NT can be wet-induced crosslinking after the cable is extruded after adding DFDB-5480 NT catalyst masterbatch. If black cables are required for UV protection, it is recommended to add DFDB-5410 BK carbon black masterbatch. Since the catalyst and carbon black masterbatch are transported separately with the DFDA-5451 NT copolymer, these components are very stable during the shelf life. The cross-linking reaction can only occur under the condition that the components are in contact with the wet content after melting and mixing. specifications when DFDB-5480 NT is used or DFDB-5410 BK is selected for cross-linking, products DFDA-5451 NT can generally meet the requirements of cables not higher than 1 kV in the following standards: UL 854 ICEA:S-66-524 Canadian Standards Association (CSA) RW90 IEC:60502-1

Additional Information
Storage: The environment or conditions of storage greatly influences the recommended storage time. Storage under extreme conditions may affect the quality, processing, or performance of the product. Storage should be in accordance with good manufacturing practices. The recommended storage conditions are dry conditions with temperatures between 50°F and 86°F (10°C and 30°C). When stored under these conditions, the product may be used by the customer for up to one year from the date of sale or two years from the date of manufacture, whichever comes first. It is recommended that the practice of using the product on a first-in / first-out basis be established.

Extrusion instructions
DFDA-5451 NT will extrude with excellent surface quality and without extrusion scorch if the accompanying catalyst masterbatch, DFDB-5480 NT and the carbon black masterbatch, DFDB-5410 BK, are kept dry. It is especially recommended that the catalyst and carbon masterbatches be dried at 140°F-160°F (60°-70°C) for four to six hours using dehumidified air prior to mixing and extrusion. Melt temperatures in the range of 300°F-450°F (150-230°C) have been successfully used.After extrusion of the appropriate mixture of this product and its catalyst and carbon black masterbatches, cross-linking can be achieved by allowing moisture to diffuse into the product. Most fabricators find that a hot water bath or sauna works best. To achieve a hot creep elongation of 100%, the typical times shown below are required (45 mil [1.1 mm] wall on 14 AWG [2.1 mm²] wire). 70°C: 10 hrs 90°C: 3.5 hrs Specific recommendations for your particular equipment and conditions can be determined by contacting your local Dow Wire and Cable sales representative.
