| Cleanliness: The cleanliness of DOW ENDURANCE HFDK-4201 SCsb is assured through double cleanliness testing using both traditional tape testing as well as high resolution pellet checking. The specifications are set to exclude contaminants >100µm. Contaminant counts/kg of particles < 100µm are reported. 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. Packaging: DOW ENDURANCE™ HFDK-4201 SCsb can be delivered in Dow's UNICLEAN™ big bags, or in 1000 kg octabins. |

| The DOW ENDURANCE™ HFDK-4201 SCsb can be processed with melt temperatures of 115 -140°C, preferably 135°C for HV applications.Screen packs are only required if there is a need to improve the homogenization of the melt or as protection from contamination entering during unloading and processing. If desirable DOW ENDURANCE HFDK-4201 SCsb allows the use of fine mesh screens (400mesh/65µm) without causing pressure build up over time. The use of 250 mesh screens (100µm) is common.At start-up, it is recommended to use DFDK-4850 transition compound to achieve stable extruder conditions. |
