4) General Application Capsule Filters Hydrophilic ePTFE Membrane

Summary

Source General Application Capsule Filters Hydrophilic ePTFE Membrane from MS factory for aqueous and mixed aqueous-organic filtration where PTFE chemical durability must combine with instant water wetting. The surface-modified hydrophilic ePTFE membrane delivers high flow at low pressure drop, 100% integrity testing and low-extractables construction compliant with FDA 21 CFR and EU 10/2011.

Introduction

Order China General Application Capsule Filters Hydrophilic ePTFE Membrane from MS for aqueous liquids that need a membrane wetting out instantly without alcohol pre-treatment. The hydrophilic surface modification preserves PTFE's chemical and thermal resistance while allowing water-based fluids to enter the pore structure freely. This suits beverage clarification, pharmaceutical intermediate filtration and process water polishing where compatibility and low extractables matter.

Buyer Comparison: Hydrophilic ePTFE vs Alternatives

If your aqueous stream contains oxidants, acids or co-solvents, hydrophilic ePTFE provides the widest compatibility.

If you need a cost-effective membrane for clean neutral buffers, Nylon or PES is often considered.

If you want low protein binding with broad aqueous and mild solvent resistance, hydrophilic PVDF is a common alternative.

Application Notes:

Aqueous FocusBeverages: vinegar, juice, wine, beer and edible oils handled with PTFE-level stability.

Pharmaceutical intermediates: aqueous buffers with organic modifiers or oxidants.

Process water: polished for clarity without introducing taste or odor compounds.
