Overview
Anhui Xinfulong's PFA (Perfluoroalkoxy) Electronic-Grade Piping is precision-engineered for the most demanding high-purity fluid handling applications in semiconductor manufacturing, wet electronic chemicals, pharmaceutical, and advanced technology industries. Manufactured from premium electronic-grade PFA resin, our piping systems deliver exceptional purity, chemical resistance, and thermal stability — making them the preferred choice for transporting ultra-pure water, high-purity chemicals, and aggressive media in critical process environments.
PFA piping is widely recognized as the "golden vascular system" of semiconductor production lines, providing the contamination-free delivery infrastructure essential for achieving high chip yields in advanced nodes down to 7nm, 5nm, and beyond. With metal ion extractables below 0.1 ppb and compliance with SEMI F57 standards, our PFA electronic-grade piping ensures the highest level of process purity.

Technical Specifications
Manufacturing & Quality Standards
Manufacturing Excellence
Cleanroom Production
All critical manufacturing processes are carried out in strictly controlled cleanroom environments — Class 1,000 for extrusion, Class 10,000 for injection molding, and Class 100 for final packaging. This ensures the highest levels of purity and minimizes contamination risks throughout the production process.
Rigorous Quality Testing
Every batch undergoes comprehensive quality testing including:
-
Metal Ion Extraction Testing — Agilent ICP-MS analysis to ensure ultra-low ionic contamination
-
Particle Release Testing — RION Particle Analyzer for UPW particle count
-
High-Temperature and Burst Testing — Verifying safety and reliability under extreme conditions
-
SEMI F57 Extractables Testing — Full compliance with semiconductor industry standards
