PTFE Micro Porous Filtration Tube

PTFE micro porous filtration tube is a high-performance filtration component made from 100% virgin PTFE fine powder. Through a proprietary elasticity process, we produce a homogeneous micro-porous structure that delivers consistent pore size distribution and reliable filtration performance. This tube is chemically inert, resistant to nearly all industrial chemicals, and operates effectively across a temperature range of -80 °C to +250 °C. It is suitable for filtering both liquids and gases, including aggressive chemical media where metal or polymer filters would fail.

In our manufacturing and field testing, PTFE micro porous filtration tubes have been installed in chemical water treatment lines, pharmaceutical solvent filtration systems, and corrosive liquid transfer processes. A typical installation in a chemical plant's acidic wastewater line operated continuously for 12 months without measurable degradation in filtration efficiency, maintaining a flow rate above 95% of the initial value.

Features

• Manufactured from 100% virgin PTFE fine powder with no additives or fillers
• Homogeneous micro-porous structure created by a controlled elasticity process
• Chemically inert and anti-corrosive against acids, bases, and organic solvents
• Withstands extreme temperatures from -80 °C to +250 °C without structural failure
• Effective filtration of both aqueous and gaseous media
• Pore size range 0.2–100 μm with 60–80% porosity for high flux
• Tensile strength of 10 MPa provides mechanical durability under pressure
• Non-stick, low-friction surface resists fouling and simplifies cleaning

Applications

• Chemical water filtration in acidic, alkaline, and solvent-based processes
• Chemical gas filtration for corrosive vapors and reactive gas streams
• Pharmaceutical industry filtration where purity and chemical resistance are critical
• Corrosive liquid filtration in electroplating, PCB manufacturing, and metal finishing
• Wastewater treatment in mining, semiconductor, and municipal applications

In a PCB manufacturing facility, our PTFE filtration tubes were deployed to handle strong acid wastewater. Compared to the previous filtration method, the PTFE tube reduced filter replacement frequency by approximately 40% over a 6-month evaluation period, significantly lowering maintenance downtime.
