摘要
介绍了热塑性弹性体PEBA材料,作为嵌段型共聚物的PA改性材料,除具有聚酰胺本身优异的机械性能和电气性能外,提高了材料的柔顺性、出众的低温抗冲击性能和优异的加工性能,将该种材料成功的运用在生产柔性电缆护套材料中,并对其加工工艺进行了探讨。
The thermoplastic elastomer PEBA （Polyether Block Amide ） material was introduced, as a block copolymer of PA modified materials, in addition to keep the polyamide itself excellent mechanical and electrical property, and that had been improved the flexibity, superior lowtemperature impact resistance and excellent processing performance. The material was used in the production for jacket material of flexible cable and its process was discussed.
