Hydrophobic PET Membrane Spike Venting Caps from China Suppliers - High Flow Rate & Oleophobic Performance Factory
Product Introduction
Medical devices require vents to keep their internal pressure in balance with the ambient pressure, maintaining pressure balance within the infusion set and avoids the deformation of rigid plastic containers and interruptions in flow of fluids.
The vents that use our Hydrophobic PET membrane could protect the fluid path from particles, aerosol and bacterial contamination, avoid risk to human health, maintaining sterility of an IV set and bottle.
Because of its unique constructure and manufacturing process, Hydrophobic PET membrane has the same performance and property on both surfaces. Every fiber deep inside the spike venting membranes is hydrophobic and oleophobic, the outstanding oleophobic properties can effectively prevent permeation of lipids and alcohols drugs like TPN, D-Mannitol etc., which consequently improve the safety of infusion medications and reduce the feedback of adverse clinical events.

Frequently Asked Questions
Q1: What is the main function of the Hydrophobic PET membrane in medical devices?
A1: It acts as a pressure-balancing vent that protects the fluid path from particles, aerosol, and bacterial contamination, maintaining sterility in IV sets and preventing rigid containers from deforming.
Q2: How does the membrane perform against lipids and alcohol-based drugs?
A2: Thanks to its unique structure, every fiber deep inside the membrane is hydrophobic and oleophobic, which effectively prevents the permeation of lipids and alcohol drugs such as TPN and D-Mannitol.
Q3: What are the key specifications for thickness and pore size?
A3: The standard specifications feature a thickness of 0.20mm to 0.30mm, a pore size of 3μm, and a Water Bubble Point (WBT) of 28kpa.
Q4: What precautions should be taken during assembly and welding?
A4: The membrane should be handled with care. The recommended welding temperature is 210℃. Please avoid using ultrasonic welding, and be aware that glue or cyclohexanone can clog the material.
Q5: In what formats can this membrane be ordered?
A5: It is available under Material type 'E', with a pore size of 050 and thickness of 200~300μm. It can be supplied in rolls, individual pieces, or customized dimensions.
