HFDB-4202 EC meets the strictest standards for cleanliness established for an unfilled, crosslinkable cable insulation compound. Throughout the production process, the product is tested to ensure a high level of cleanliness. Extruded tapes are scanned by an automatic inspection system in a class 10,000 clean room. The purity data is managed using an acceptance sampling plan, which ensures that the product in the shipping container meets or exceeds extra-clean standards. Maximum Allowable in 1.6 kg Tape: DOW ENDURANCE HFDB-4202 EC 5-9.9 mils (125-250 μm): 3 10-25 mils (250-630 μm): 0 >25 mils (>630 μm): 0 In addition, as DOW ENDURANCE HFDB-4202 EC is packaged, a continuous side stream of pellets is analyzed using an electronic pellet inspector to comply with ICEA specification S-94-649-2004 section K2.2. A review of detected contamination is incorporated into our EC quality program. 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. If proper warehousing and storage temperatures [dry conditions, between 50°F and 86°F (10°C and 30°C) in temperature] are utilized, this product may be stored by the customer for up to one year. In general, the product should be used within two years of the date of manufacture. It is recommended that the practice of using the product on a first-in / first-out basis be established. |

| DOW ENDURANCE HFDB-4202 EC provides excellent surface finish and outstanding output rates over a broad range of conditions. For optimum results, melt extrusion temperatures in the range of 240 to 285°F (116 to 140°C) are recommended, although higher melt temperatures are possible on certain equipment with due care. Generally, a 60-40-20 screen pack is recommended. However, specific recommendations for processing conditions can be determined when the application and type of processing equipment are known. |
