PFA Tube
ESI's PFA tubes are made from high-purity resin, ensuring clean and stable fluid transfer. They offer excellent resistance to heat and chemicals, making them suitable for demanding or corrosive environments. The smooth, non-reactive inner surface helps prevent particle buildup and contamination, while their translucent wall allows quick visual checks of flow conditions. Because of their purity and reliability, PFA tubes are widely used in semiconductor, pharmaceutical, and laboratory systems.
Key Features
High Purity and Clean Surface
Manufactured from high-purity PFA resin with minimal extractable ions, the tubing prevents metal contamination and supports cleanroom use in semiconductor and pharmaceutical processes.
Superior Chemical Resistance
Resistant to strong acids, bases, and solvents, PFA tubing maintains material integrity even in aggressive chemical environments.
High Temperature Resistance
Performs reliably from cryogenic levels up to 260ºC, maintaining physical stability and chemical resistance across a wide temperature range.
Smooth Interior Surface
With a surface roughness of ≤ 0.25 µm (per SEMI F52-1101), the PFA tubes reduce particle adhesion and residue buildup, improving flow cleanliness and consistency.
Translucent Wall Design
The semi-clear material allows easy visual monitoring of fluid flow or bubbles, aiding quick inspection during operation.
Excellent Processability
Melt-processable PFA can be heat-welded, flared, or bent to precise shapes – ideal for complex piping layouts in semiconductor and laboratory equipment.
Applications
Semiconductor Manufacturing
Used for chemical delivery, DI water, and wafer cleaning lines requiring ultra-high purity.
Pharmaceutical & Biotechnology
Transfers sterile or reactive fluids safely in cleanroom environments.
Laboratory & Research
Ensures accurate testing and analysis by preventing sample contamination.
Chemical Processing & Energy
Handles corrosive acids, solvents, or high-purity water in production and utility systems.
