Nominal property values above represent tests on molded stress-relieved slabs. Cure times were 15 minutes at 175°C.Storage The environment or conditions of storage greatly influences the recommended storage time. Storage should be in accordance with good manufacturing practices. If proper warehousing and storage temperatures [dry conditions, between 50°F and 75°F (10°C and 23°C) in temperature] are utilized, this product may be stored by the customer for up to one year. It is recommended that the practice of using the product on a first-in / first-out basis be established. Storage under extreme conditions may affect the quality, processing, or performance of the product. Storage at elevated temperatures should be avoided to prevent blocking. Pellets are readily friable should blocking be experienced.

Инструкции по экструзии
DOW ENDURANCE™ HFDA-0693 BK LS provides excellent surface finish and outstanding output rates over a broad range of conditions. For optimum results, use melt extrusion temperatures in the suggested range of 235 to 255°F (115 to 125°C) to avoid pre-cure or scorch. Extruder barrel settings of 110°C (230°F) are suggested as a starting point while learning to process DOW ENDURANCE™ HFDA-0693 BK LS. Specific machine settings will depend on the extruder design and must be established through conventional practices. The curing temperature should be carefully controlled, and the maximum surface temperature in the CV tube should not exceed 527°F (275°C) for optimum results. Extruder feed-throat cooling is recommended to improve feed efficiency.DOW ENDURANCE™ HFDA-0693 BK LS can be handled in the same fashion as other vulcanizable polyolefin semiconductive materials. It is available in regular or UNICLEAN™ boxes and can be air-conveyed at transport temperatures of 75°F (24°C) or below. Do not use a heated dryer with HFDA-0693 BK as pellets may fuse. During shutdowns exceeding one hour, DOW ENDURANCE™ HFDA-0693 BK LS pellets should be removed from potentially warm hopper bins to avoid fusing.
