DFDA-4850 NT是一种低密度、热塑性、未填充的聚乙烯化合物,设计用于启动和关闭中高压(5千伏及以上)电力电缆绝缘挤出机。它具有这些应用所需的高度清洁度。DFDA-4850 NT是一种标称的2.0熔融指数、0.92密度、高压低密度聚乙烯树脂,该树脂已通过与HFDB-4201 EC、HFDB-4201 SC和HFDB-4202 EC兼容的抗氧化系统稳定。清洁度要求DFDA-4850 NT必须符合陶氏化学公司针对未填充热塑性绝缘净化型化合物制定的严格清洁度标准。产品经过测试以确保高水平的清洁度。在10000级洁净室中,通过自动检测系统对颗粒样品进行目视检查和挤压胶带扫描。纯度数据采用验收抽样计划进行管理,以确保装运容器中的产品符合或超过要求的清洁度标准。 DFDA-4850 NT is a low density, thermoplastic, unfilled polyethylene compound designed for starting-up and shutting-down medium and high voltage (5 kV and higher) power cable insulation extruders. It has a high degree of cleanliness required for these applications. DFDA-4850 NT is a nominal 2.0 melt index, 0.92 density, high pressure LDPE resin that has been stabilized with an antioxidant system that is compatible with HFDB-4201 EC, HFDB-4201 SC and HFDB-4202 EC. Cleanliness Requirements DFDA-4850 NT is required to meet strict standards for cleanliness as established by The Dow Chemical Company for an unfilled, thermoplastic insulation purge-type compound. The product is tested to ensure a high level of cleanliness. Pellet samples are visually inspected and 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 the required cleanliness standards. |
