Futureway PTFE venting membrane is a general-purpose microporous polytetrafluoroethylene (PTFE). The product has inherent hydrophobicity and chemical resistance. It can prevent water from passing but allow gas to pass freely. It is in the battery pack explosion-proof valve provide pressure equalization effect.
Product Description
PTFE venting membrane is a universal microporous polytetrafluoroethylene (PTFE).
Characteristics and advantages:
• With excellent chemical compatibility and thermal stability, it can handle almost any corrosive fluid;
• Rugged, self-supporting, and usually does not require non-PTFE polymer adhesives that can impair performance;
• It is possible to filter the aqueous solution using a pressure exceeding the water inlet pressure of the membrane or with the aid of a wetting agent such as ethanol.
Application
With inherent hydrophobicity and chemical resistance, it can prevent water from passing but allow gas to pass freely.
These characteristics make PTFE venting membrane an effective waterproof and breathable material, which can provide a pressure equalization effect in the explosion-proof valve of the battery pack.
