国内首套SEPS工业化装置投产

2017-09-07 07:17:08   中国青年网

湖南日报9月6日讯(记者 王晴 通讯员 彭展 徐亮亮)近日,中国石化巴陵石化向外宣布,该公司已建成投产国内首套年产2万吨热塑橡胶SEPS(氢化苯乙烯/异戊二烯共聚物)工业化装置,聚合加氢单元首次投料开车取得圆满成功。这标志着巴陵石化成为全球第三家采用具有自主知识产权核心技术工业化生产SEPS的企业,填补我国SEPS产品研发生产的空白,打破美国和日本企业长期垄断的局面,在热塑橡胶成套技术创新研发中具有里程碑意义。

SEPS是有“绿色橡胶”美誉的热塑弹性橡胶SIS加氢后的高端环保“升级版”产品,不但保留了SIS优异的应用性能,还在产品耐热、耐光及耐热氧等抵抗环境因素的能力方面有显著提高,在透明性、弹性方面更优。它可作为确保通信电缆、光缆防潮、绝缘及信号稳定的填充膏,可广泛用于医疗、电绝缘、食品包装以及复合袋的层间黏合,并在金属与塑料黏结上有独到之处,还可用于眼镜及其他光学材料,具有良好的透明性、柔韧性及抗冲击性。

SEPS自上世纪80年代实现工业化生产以来,全球只有美国和日本各一家企业有该产品供应,我国SEPS产品全部依赖进口,价格高昂。
