The core technology behind Ventrase breathable membranes is expanded polytetrafluoroethylene (ePTFE). Through controlled expansion processing, PTFE forms a unique microporous structure that allows air and vapor transmission while blocking liquid water and contaminants.
This waterproof breathable technology enables pressure equalization and environmental protection for packaging, electronics, automotive components and industrial equipment operating in demanding conditions.
- Waterproof protection against liquid penetration
- High airflow performance for pressure equalization
- Hydrophobic structure with excellent water repellency
- Chemical resistance for harsh environments
- Wide temperature resistance and long service life
How ePTFE Breathable Membrane Works
Millions of interconnected micropores create airflow channels. These pores allow gas molecules and vapor to pass while preventing liquid water penetration.
The low surface energy of PTFE provides excellent water repellency and protects sensitive components from moisture and contamination.
Breathable membranes balance internal and external pressure caused by temperature changes, altitude variation or gas generation.
ePTFE materials maintain stable performance against chemicals, dust and challenging industrial environments.
