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.

用途 may also be described by the following terms: Low Voltage Insulation, 电线电缆应用，电线电缆用途.

This plastic material has 3 certifications from the following agencies (the number in parentheses shows the number of certifications for that agency): IEC (1), UL (1), ICEA (1).

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
