（记者 王晓波） 每经AI快讯，有投资者在投资者互动平台提问：1、公司的核心优势在于电石-醋酸乙烯-聚乙烯醇等化 工新材料，可是公司名称为什么要叫环保，能否改为双欣科技或者双欣化工；2、公司PVB膜性能很 好，耐高低温、抗辐射，很适合商业航天和太空光伏这类尖端领域，请问公司在这方面有探索或计划 吗？ 双欣环保（001369.SZ）1月29日在投资者互动平台表示，首先非常感谢您对公司名称方面提出的合理化 建议，我们会将您的建议及时向公司管理层反馈，进行认真研究；第二，公司PVB功能性膜项目2025年 第四季度进入试产阶段，目前还处于市场认证阶段，公司将持续加大技术创新力度，推动主营业务向高 品质、多品种、差异化、高附加值方向发展，提高公司全球竞争力。 ...

再者，双欣环保的核心竞争力源于全产业链布局构建的成本壁垒与高端化转型形成的技术优势。公司深 耕PVA领域16年，打造了"石灰石—电石—醋酸乙烯—聚乙烯醇—下游高端产品"的完整循环经济产业 链，87万吨/年电石产能实现上游原料自给，使得PVA出厂价较行业平均水平低10%-15%，在价格波动 中具备更强的抗风险能力。据行业统计数据，公司PVA年产能13万吨，2024年产量达11.69万吨，位居 行业前三，国内市场占有率稳定在13%，扎实的产业根基为高端化拓展提供保障。技术创新方面，公司 累计获得260项授权专利，参与制定国家及行业标准13项，年产1.6万吨PVB功能性膜与700万平方PVA 光学膜项目已进入试生产阶段，前者可打破外资在高端夹层膜领域的垄断，后者实现偏光片核心材料国 产替代，两大业务成为盈利增长新引擎。 2026年1月26日，A股市场呈现震荡调整态势，上证指数微跌0.09%，深证成指下跌0.85%，而双欣环保 （001369.SZ）稳守170亿市值，截至收盘成交2.53亿元，换手率8.30%，总市值达172.97亿元。日前换手 创年内新高以及稳守170市值接连表现的背后，或是化工行业迎来政策与周期共 ...
