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.

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.

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.
