我国聚四氟乙烯领域近年来发展迅速,通用级聚四氟乙烯已经出现产能过剩的现象,但由于核心技术被掌控,以高压缩比聚四氟乙烯分散树脂为代表的高端品种却还依赖进口。我国企业需重点关注聚合方法和氧化还原引发体系的改进,在国外专利的重重围困中找到突破口,实现产业的转型升级。聚四氟乙烯:发展迅速差距仍大申请量增长迅速21世纪之前,我国在聚四氟乙烯领域还较为落后,国外公司也不太重视在我国的专利布局,导致其申请量一直增速较慢。进入21世纪之后,随着我国企业在聚四氟乙烯领域的快速 China’s rapid development in the field of PTFE, general-purpose PTFE has overcapacity phenomenon, but because of the core technology is in control, high compression ratio PTFE dispersion resin, represented by the high-end varieties are also dependent on imports . Chinese enterprises need to focus on polymerization methods and redox initiation system improvements, find a breakthrough in the heavy siege of foreign patents to achieve industrial restructuring and upgrading. Teflon: the rapid development of large applications are still growing rapidly Before the 21st century, our country is still relatively backward in the field of PTFE, foreign companies do not attach great importance to the layout of the patent in our country, resulting in its application has been growing slower . Into the 21st century, with the rapid development of China’s enterprises in the field of PTFE
