FREQUENT QUESTIONS

ePTFE Venting Membrane Technical Questions

What is an ePTFE venting membrane?

A microporous PTFE-based material that allows air passage while blocking liquids, dust, and contaminants.

How does a venting membrane work?

It balances pressure differences inside sealed containers while maintaining waterproof and chemical barrier properties.

What is WEP (Water Entry Pressure)?

WEP defines the pressure at which water penetrates the membrane, indicating waterproof performance strength.

Can airflow be customized?

Yes. Air permeability can be adjusted by membrane structure, thickness, and pore density.

Do you provide OEM vent liners?

Yes. We support die-cut vent liners, adhesive membranes, and custom packaging integration.

Which industries use this membrane?

Chemical packaging, agrochemicals, lubricants, electronics, and industrial liquid containers.
