SI-LINK™ DFDA-6451 NT

Product Handling

• SI-LINK® PE base resins are inherently crosslinkable, but the reaction is extremely slow when the crosslinking catalyst is not present. Therefore, we recommend that under good warehouse conditions - (dry conditions, between 10 and 30 °C in temperature), SI-LINK® PE base resins should be used within one year of purchase. Opened containers should be used promptly to avoid moisture pickup or contamination.

DFDA-6451 Natural will extrude with excellent surface quality and without extrusion scorch if the accompanying catalyst masterbatch, DFDB-5480 Natural, is kept dry. It is especially recommended that the catalyst masterbatch 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°C-230°C) have been successfully used.

After extrusion of the appropriate mixture of this product and its catalyst masterbatch, crosslinking can be achieved by allowing moisture to diffuse into the product. Most fabricators find that a hot water bath or sauna work best. Most manufacturers aim for a hot creep elongation of 100%. The actual time to achieve this degree of crosslinking is dependent on the insulation thickness and the water or sauna temperature.
