See the last page for disclaimer最新动态➢技术装备先进。公司CPE、烧碱、双氧水以及PVDC、六氯环三磷腈、苄索氯铵等产品生产技术均为国内最先进的生产工艺，且均为2021 年以后的新建装置。CPE 独家采用德国赫司特盐酸相法工艺，环保优势显著。烧碱装置采用国内最先进的生产工艺，2024、2025 连续两年入选省级重点行业能效“领跑者”名单。2023 年6 月，公司独家引进了韩国SK 集团PVDC 工业生产技术，目前处于世界领先水平。六氯环三磷腈，公司是目前是国内唯一实现量产、产能最大的生产企业，实现进口替代。动向解读➢公司以氯碱为龙头，新的循环经济链逐渐搭建成型。公司属化学原料和化学制品制造业，主要经营活动为生产、销售氯化聚乙烯、烧碱和双氧水等；实现“氯碱平衡”，氯碱装置产出的烧碱外卖兼顾为园区提供原料；副产液氯为公司生产CPE、PVDC 主要原料之一；副产氢气被用于生产双氧水或通入燃气锅炉自产蒸汽；PVDC（聚偏二氯乙烯），以氯乙烯加氯气生成三氯乙烷，然后经过液相脱氯化氢的反应制造偏二氯乙烯，随后由偏二氯乙烯为原料聚合制备聚偏二氯乙烯。六氯环三磷腈，以五氯化磷为主要原料，通过溶解、合成、过滤、浓缩、结晶、干燥工序产出产品；苄索氯铵，以对特辛基苯酚与二氯二乙醚为主要原料，通过醚化反应、取代反应、然后离心、烘干得到产品。根据2025 年
亚星化学年报，4.5 万吨/年高端新材料（PVDC）项目的生产装置已开始试生产，现已产出合格产品。500 吨/年六氯环三磷腈和500 吨/年苄索氯铵项目六氯环三磷腈和苄索氯铵装置均已全链路打通，产品全部达标。➢含氯聚合物前景广阔。1）随着人们生活水平的提高，各类包装材料的需求会快速增加，聚偏二氯乙烯（PVDC）树脂、薄膜及其他产品将逐步进入高保鲜要求的包装领域。国内聚偏二氯乙烯树脂的生产、加工和应用已进入一个相对成熟的阶段，将对食品包装特别是肉食品包装产生深远的影响，并因其优异的性价比，将会在食品、医药、化工等领域获得广泛的应用。2）六氯环三磷腈是合成聚磷腈高聚物的关键原料和中间体。聚磷腈材料具有耐水、耐溶剂、耐高低温、阻燃等优异性能，广泛应用于特种橡胶、低温弹性体、阻燃电子材料、生物医学材料等领域，其中高效的五氟乙氧基环三磷腈由于高效阻燃的有机氟与电化学稳定的环三磷腈协同作用，在高压锂离子电池中有着广泛的应用前景。磷腈系列产品不但可以添加入锂电池电解液，还可以作为正负极材料使用，以改善电池的安全性。3）苄索氯铵在医药、日化、化妆品等行业的医药提纯、中间体、消毒、杀菌等领域应用广泛。风险提示➢化工行业周期、市场竞争、原材料价格波动等。Charles Zhuang 庄怀超SFC CE: BTE209微信: zhuangcharles; 电话: (852) 9748 7114;环球富盛理财有限公司
