High purity PFA (Perfluoroalkoxy resin, CAS 26655-00-5) is a fully fluorinated copolymer of tetrafluoroethylene and perfluoropropyl perfluorovinyl ether, manufactured on dedicated high-purity production lines.

Compared with ordinary PFA, high purity grade has significantly lower metal ion and fluoride ion precipitation, and lower total organic carbon release. It maintains all excellent properties of standard PFA: PTFE-equivalent chemical resistance and service temperature, melt processability, and higher mechanical strength than FEP. It fully meets the strict purity and reliability requirements of semiconductor, aerospace and medical device industries, and is suitable for chemical supply tubing and injection-molded parts in semiconductor fabs. It can be processed into sheets, rods, tubes, valves, flowmeters, wafer carriers, filters and various high-purity components, and is the core basic material for high-end wet process and fluid delivery systems.

High-end Chemical Anti-corrosion Components: Used in high-purity chemical, pharmaceutical and fine chemical industries to manufacture anti-corrosion linings, pipelines, pump valves and reaction equipment components. Its ultra-high purity avoids secondary pollution to materials, and its excellent corrosion resistance greatly extends equipment service life.

5. Analytical & Testing Equipment Parts: Used to manufacture fluid components for analytical instruments, liquid chromatography systems and detection equipment. Its low TOC and low ion release will not interfere with test results, ensuring detection accuracy and stability.

6. High-purity Sheet, Rod & Semi-finished Products: Processed into high-purity PFA sheets, rods and various semi-finished products, which are machined into customized special-shaped parts for semiconductor, medical and scientific research fields, adapting to small-batch customized high-purity component demands.

   

A1: The core difference lies in impurity control. High purity PFA is produced through dedicated clean production lines, with extremely strict control over metal ions, fluoride ions and total organic carbon. For example, extractable iron is controlled below 3ppb, which is far lower than ordinary PFA. It can avoid ion contamination to high-purity chemicals and wafers, so it is suitable for semiconductor, medical and other high-demand fields. Ordinary PFA is mainly used for general industrial anti-corrosion scenarios.

A2: The metal ions (Fe, Ni, Al) are tested by immersion extraction with 20% hydrofluoric acid at 25℃ for 1 hour; fluoride ions are tested by immersion in ultrapure water at 60℃ for 4 hours; TOC is tested by immersion in ultrapure water at 85℃ for 24 hours. These test conditions simulate the actual use environment of semiconductor wet process, and can truly reflect the ion release performance of materials in practical application.

A3: Yes. High purity PFA has similar processing performance to ordinary PFA, and can be processed by conventional compression molding, extrusion and injection molding equipment. To avoid impurity contamination, it is recommended to use a dedicated screw and barrel for high-purity materials, and clean the equipment thoroughly before processing to ensure the purity of finished products.

A4: High purity PFA is compatible with most semiconductor process chemicals, including various concentrations of acids, alkalis and organic solvents. For special high-temperature strong oxidizing systems, it is recommended to conduct compatibility tests in advance to confirm the long-term stability of the material under specific working conditions.

A5: High purity PFA should be stored in the original sealed clean packaging, placed in a clean, cool and dry environment, avoid direct sunlight, moisture and dust pollution. It is forbidden to open the package in non-clean environment to prevent environmental impurities from contaminating the resin and affecting the purity of finished products.

A6: Medical grade high purity PFA meets relevant medical material standards and has good biocompatibility, and can be used for medical device components and pharmaceutical fluid delivery systems after corresponding certification. For specific medical applications, please select the corresponding grade and complete the necessary quality evaluation according to the actual use scenario.
