Sterlitech PTFE Unlaminated Membrane Filter Sheets, 1.0 Micron, Hydrophobic, 254mm x 3000mm

Sterlitech PTFE unlaminated membrane filters are constructed from pure expanded polytetrafluoroethylene (ePTFE), forming a uniform, microporous structure ideal for high-performance filtration in aggressive environments. These hydrophobic, unsupported membranes are designed for sterilisation and venting of air, gases, and solvent-based systems where conventional filters are unsuitable.

They are chemically and biologically inert, stable up to 260°C, and highly resistant to concentrated acids, bases, and solvents, making them well-suited for applications involving corrosive vapours, sterilising gas lines, or protecting instrumentation from moisture ingress.

Key Features

Unsupported, hydrophobic ePTFE membrane
Excellent resistance to strong acids, bases, and solvents
Uniform pore structure and consistent membrane thickness
High thermal stability up to 260°C (500°F)
Ideal for sterilisation and venting of gases and vapours
Biologically inert and chemically non-reactive

Precision Structure for Harsh Environments

Manufactured through a patented biaxial stretching process, these unlaminated PTFE membranes achieve high porosity while maintaining exceptional dimensional stability and chemical durability. Their hydrophobicity makes them especially effective in air or gas filtration systems containing water vapour, where liquid ingress must be avoided without compromising flow performance.

Notes:
1. Airflow values calculated assuming linear relationship between volumetric airflow and differential pressure.
2. Water flows measured after prewetting with alcohol and calculated assuming linear relationship between flow and differential pressure.
3. Bubble points for 0.2µm, 0.45µm, and 3.0µm pore sizes measured using IPA; all others measured using ethanol.
