This article introduces a high-end electronic-grade PFA fluorine-lined product that breaks semiconductor industry technical barriers. Built on Class 10,000 dust-free production and 99.999% high-purity PFA resin, it adopts German precision extrusion lines to achieve ultra-low inner wall roughness and 12% lower flow resistance. With wide temperature resistance and 3,000-hour stable delivery of nitric acid fully meeting SEMI standards, it fills the domestic gap in high-end electronic-grade fluorine materials. It supports semiconductor core material localization and empowers the upgrading of China’s electronic manufacturing industry.
