Supply and demand status of China's PTFE industry in 2019, with a wide range of industry applications
一、聚四氟乙烯生产工艺流程分析
聚四氟乙烯（PTFE）也被称为F-4，是现阶段全球范围内耐腐蚀性能最为理想的材料之一，俗称“塑料王”。该材料一般划分为两类，分别是悬浮聚四氟乙烯和分散聚四氟乙烯。
聚四氟乙烯产业链上游原材料是萤石，萤石粉与浓硫酸在转炉中反应，生成的炉气经过洗涤、冷凝及精馏后，经过脱气塔除去轻组分制得无水氟化氢；无水氟化氢、氯仿在催化剂的作用下反应，反应物经分离、洗涤、精馏得到精制二氟一氯甲烷（制冷剂R22），R22经水蒸气稀释裂解后，生成含四氟乙烯单体及少量全氟丙烯、微量含氟高沸物、氯化氢等的裂化气，
通过降温、水洗、碱洗以除去氯化氢后，裂化气再经多次脱水、压缩及干燥后进入脱气塔，其中塔釜物料进入四氟乙烯精馏塔以完成对四氟乙烯单体的检测及收集。精制得到的高纯度四氟乙烯单体，经汽化后进入聚合反应釜，辅以添加全氟辛酸等作为活化剂，以合成高分子量四氟乙烯树脂。

随着“5G”时代到来，市场对高性能聚四氟乙烯需求不断增长，由于其特殊的分子结构，使其能够抵抗几乎所有的强酸、强碱和有机溶剂，并具有良好的低介电性能、低损耗因子；从下游需求分布来看，石油化工占比33%，机械行业占比24%，电子电气占比12%，轻工业与纺织业占比16%，建筑、航空航天分别占比4%与2%，其他行业占比9%。

二、中国聚四氟乙烯行业市场现状分析
目前，已产业化的含氟聚合物主要包括PTFE（聚四氟乙烯）、FEP（全氟乙烯丙烯共聚物）、PVDF（聚偏氟乙烯）、PVF（聚氟乙烯）及FKM（氟橡胶）等。PTFE系列是最重要的含氟聚合物，产销额占据全部含氟聚合物的一半以上。

近年来我国在聚四氟乙烯领域发展迅速，产量从2011年5.31万吨增长至2019年9.1万吨，年均复合增长率达到6%，产能占比全球40%左右。

近年来随着5G基站的快速发展，PTFE在覆铜板、同轴电缆、节能环保等领域的应用不断扩大。进一步带动了PTFE的市场需求，据统计，截至2019年我国聚四氟乙烯消费量为7.63万吨，同比增长13.7%。
资料来源：公开资料整理
2019年我国PTFE进口量约6800吨，其中大部分为高端PTFE改性产品，以此满足下游行业需求。我国PTFE已出现产能结构性过剩现象，注塑级中低端产品严重过剩，产能利用率低下，而以高压缩比聚四氟乙烯分散树脂为代表的的高端品种却还依赖进口，进口均价维持在1万美元/吨以上。目前国内PTFE低端产品价格在4万元/吨左右，中端产品4~6万元/吨，高端产品价格在6万元/吨以上。

目前，我国已经成为全球PTFE主要生产国和供应国。自2010年至今维持在2万吨/年左右的出口量水平，2019年我国共出口PTFE2.1万吨，占总产量的25.6%，以注塑级的中低端产品为主。2019年我国聚四氟乙烯出口均价为8549美元/吨。

三、中国聚四氟乙烯行业竞争格局分析
2019年，国内PTFE生产企业共有12家，产能合计约14万吨/年。从分布来看，我国PTFE产能较集中，昊华集团和东岳集团合计占据国内总产能的48%，产能在1万吨以上的企业共计6家，约占总产能的83%。

四、中国聚四氟乙烯行业发展趋势
PTFE制品是一类重要的高分子产品，其应用涉及军事工业和民用的诸多领域，具有良好的发展前景。目前，在PTFE板材、管材、垫片和密封带等较低端产品方面我国已经基本占领市场，但在高端产品方面与西方发达国家仍然有较大的差距，如e－PTFE人工血管、医用缝线和心脏补片等产品在我国尚无工业化产品问世，所用产品主要依赖进口，价格昂贵。因此，进一步研究PTFE制品结构与性能之间的关系，优化制品加工工艺，开发性能优良的高端产品，发掘新的应用途径仍是今后努力的方向。
目前，国外PTFE树脂的合成工艺已达到较高水平，但是国内在高端树脂领域还有较大差距，致使国内生产高性能聚四氟乙烯材料时只能通过高昂价格进口国外聚四氟乙烯树脂，尤其是生产军工、航天和医疗等方面非常规应用材料时。因此，建议政府通过政策倾斜或专项政策资助的形式鼓励国内聚四氟乙烯树脂合成企业研发高性能聚四氟乙烯树脂以解决目前国内所面临的卡脖子问题，满足军工、环保和医疗等高端领域的需求。
