Hydrophobic PTFE Membrane Spike Vented Caps from China Suppliers | Factory Quality for Venting Applications
Product Introduction
XINNA PTFE forms a uniformly distributed and extremely fine pore structure, it’s a widely used filter media for medical air vents and closing caps. Laminated to Polypropylene (PP) or Polyethylene terephthalate (PET) support for improved durability and handling, also ensures compatibility with conventional market welding requirements and material compatibility with housing.
Because of expanded structure of PTFE itself, it allows a range of options of pore size which are customizable to meet various requirements and tailed membrane application solutions.
The outstanding oleophobic property can effectively prevent the impregnation of low surface tension liquids such as lipids and alcohol. which consequently improves the safety of infusion medications and reduces the feedback of adverse clinical events.
We strongly recommend that customers choose oleophobic PTFE air venting membrane to keep IV infusion medication safety.
To avoid complicated drugs permeation issue in clinical applications, hydrophobic and oleophobic PTFE membranes are both provided by XINNA at your option.

Warning
- Handle with care to avoid damaging the filter material.
- Sterilization by irradiation is not available.
- Glue or cyclohexanone for adhesion can clog the material itself, preventing gas from passing through.
- Avoid contact with alcohol or high-permeability solvents, otherwise, the material will become hydrophilic before it is fully dried (for Hydrophobic ePTFE only).

Frequently Asked Questions (FAQ)
What are the primary applications for XINNA PTFE membranes?
XINNA PTFE membranes are widely used as filter media for medical air vents, closing caps, vented caps with luer locks, spike air venting, high pressure injectors, gas-liquid separation, and vented drainage devices.
Why is the oleophobic PTFE membrane recommended for IV infusion?
The outstanding oleophobic property of the membrane prevents the impregnation of low surface tension liquids such as lipids and alcohol, which improves the safety of infusion medications and reduces adverse clinical events.
What supported materials are used for laminating XINNA PTFE?
XINNA PTFE is laminated to Polypropylene (PP) or Polyethylene terephthalate (PET) support to improve durability, handling, and compatibility with standard welding requirements.
Can XINNA PTFE membranes be sterilized by irradiation?
No, sterilization by irradiation is not available and should be avoided to prevent damage to the material structure.
How does alcohol or high-permeability solvents affect hydrophobic ePTFE?
Contact with alcohol or high-permeability solvents will cause the hydrophobic material to temporarily become hydrophilic before it is fully dried. Contact should be avoided to maintain performance.
Are the pore sizes and thicknesses customizable?
Yes, XINNA offers customizable pore sizes ranging from 0.2 to 3.0μm, along with customizable thicknesses and sizes in roll, sheet, or piece formats to meet your specific application requirements.
