In the semiconductor manufacturing process, wafer cleaning requires ultra pure water (UPW) with a resistivity of up to 18.2 M Ω· cm. PFA tubes are widely used in UPW conveying systems due to their extremely low ion precipitation characteristics (such as metal ion precipitation<0.1 ppb).

The semiconductor industry has very strict requirements for materials, especially in liquid transportation systems, which require materials to have high corrosion resistance, high temperature resistance, and purity. PFA tube, as a high-performance fluoroplastic, has become an ideal choice for semiconductor liquid delivery systems due to its excellent chemical stability and electrical properties.

PCTFE (polytetrafluoroethylene) gasket has become a key sealing material in semiconductor high-purity specialty gas delivery systems due to its excellent chemical inertness, extremely low gas permeability, and ultra-high purity characteristics.
