FEP Electronic Grade Pipes

Overview

Anhui Xinfulong's FEP (Fluorinated Ethylene Propylene) Electronic Grade Pipes are precision-engineered for the most demanding ultra-pure liquid delivery applications in semiconductor manufacturing, wet chemical processing, and critical fluid handling systems. Manufactured from 100% virgin FEP resin through advanced extrusion technology, our pipes deliver exceptional chemical inertness, ultra-low extractables, and superior optical clarity — meeting the stringent purity requirements of advanced semiconductor nodes including 7nm and beyond.

As semiconductor processes continue to advance toward higher integration and finer nodes, extremely high requirements are placed on the purity, stability, and system compatibility of process fluids. FEP has emerged as the material of choice for conveying ultra-pure liquids in key semiconductor processes such as wafer cleaning, etching, and CMP, due to its excellent chemical inertness, extremely low precipitation rate, and outstanding processing performance.

Compared to PTFE, FEP tubing is held to tighter tolerances and has lower gas permeability, making it particularly suitable for electronic-grade applications where precision and purity are paramount-. The translucent nature of FEP allows for effortless visual inspection of fluid flow, providing an additional layer of process control and safety.

Key Features

Ultra-High Purity & Ultra-Low Extractables

• Extremely low metal ion and organic extractables — does not cause secondary contamination to ultra-pure water and chemicals

• Meets the stringent "zero contamination" requirements of semiconductor fabrication

• 100% virgin FEP resin — no recycled material used, ensuring consistent purity

• Low permeability and moisture absorption nearly zero

Superior Chemical Inertness

• Chemically inert to virtually all acids, alkalis, solvents, and aggressive chemicals

• Excellent corrosion resistance to hydrofluoric acid, sulfuric acid, nitric acid, hydrogen peroxide, and deionized water — even at high concentrations

• Resists stress cracking — high-performance resin formulation for long-term reliability

• Non-stick, non-adherent surface prevents scale and sludge buildup

Broad Temperature Range

• Continuous service from -80°C to +200°C

• Maintains stable mechanical and chemical performance under high-temperature cleaning fluid environments

• Suitable for hot acid and hot alkali transportation systems

Exceptional Optical Clarity
