Is there a material that can allow gas to pass through, but can block the penetration of liquid? The answer is yes.
To make a material pass only gas but not liquid, the principle is to have a microporous material that is larger than the gas molecules and smaller than the smallest droplet diameter.
The most common new material at present is ptfe waterproof and breathable membrane.
PTFE waterproof and breathable membrane is made of polytetrafluoroethylene (PTFE) material through special processes such as mixing, extrusion, extrusion, calendering, and biaxial stretching.
PTFE is a new type of material that has excellent high temperature resistance, high temperature resistance, low temperature resistance, alkali resistance, anti-aging, anti-oxidation and many other advantages.
PTFE waterproof breathable membrane is a light, thin, strong and durable membrane invented and produced by Gore Company of the United States. This membrane has waterproof, breathable and windproof functions.
PTFE waterproof breathable membrane is a microporous membrane with 9 billion extremely tiny pores per square inch.
These pores are one 20,000th the size of liquid water droplets, but are 700 times larger than water molecules. Therefore, water droplets cannot penetrate them, but water vapor can be discharged.
Therefore, this kind of membrane is used as an interlayer in waterproof and breathable jacket fabrics for outdoor use.
Suzhou ptfe filter membrane manufacturer is a provider of high-efficiency separation and filtration material design solutions engaged in technology development, transfer, consulting, and services in the field of new materials; R&D, production, sales, and customization;
The ptfe materials produced by Suzhou ptfe filter membrane manufacturers use imported raw materials, and have a full set of advanced production equipment, advanced clean rooms and independent composite slitting workshops to ensure the production quality of ptfe membranes; And we use production and testing instruments imported from the United States to test the quality of PTFE membranes.
