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).

In highly corrosive environments such as chemical, semiconductor, and electroplating, the long-term stability and safety of storage tanks and containers directly determine production efficiency and operating costs. Polyvinylidene fluoride (PVDF), as a high-performance fluoroplastic, has become a key material for chemical anti-corrosion equipment due to its excellent corrosion resistance, mechanical strength, and thermal stability. Especially when it is used as the lining of fiberglass reinforced plastic (FRP) storage tanks in the form of sheet metal, it not only solves the pain points of traditional metal tanks being prone to corrosion and bulky, but also achieves a good effect of "dual material composite and doubled performance".

In the chemical industry, fluid transportation often faces highly corrosive media, high or low temperature environments, and strict purity requirements. PTFE pipes have unique advantages in these aspects. PTFE has a very strong chemical inertness and is almost unaffected by all chemicals, including strong acids, strong bases, organic solvents, and oxidants. This makes PTFE pipes very reliable when handling corrosive fluids.
