PTFE waterproof and breathable membrane is a new type of polymer waterproof material. Today we will learn about this material.
Waterproof and breathable membrane (breathing paper) is a new type of polymer waterproof material.
In terms of production technology, the technical requirements of waterproof and breathable membranes are much higher than those of ordinary waterproof materials. At the same time, from a quality perspective, waterproof and breathable membranes also have functional characteristics that other waterproof materials do not have.
The real PTFE waterproof and breathable membrane is not compounded with glue, so its temperature resistance is -40,100 degrees (EU CE standard, US ASTM standard).
It is not produced with polyethylene or TPO coating, so the air permeability should exceed 1500g/square/24 hours. If it is produced with polyethylene or TPO coating, it is basically not breathable.
Hydrostatic pressure testing shows that the hydrostatic pressure of thin waterproof and breathable membranes is at least 1.5 meters, and that of thick waterproof and breathable membranes is at least 2 meters.
Anti-aging is a must, because PP materials are easy to age under ultraviolet rays. Some fake waterproof and breathable membranes are produced with poor recycled materials. This waterproof and breathable membrane can easily age and degrade during the construction process. .
The ptfe waterproof and breathable membrane produced by Suzhou ptfe filter membrane manufacturer by mechanically stretching ptfe material can ensure the complete retention of bacteria and other impurities, while having a large flux.
The material is resistant to high temperatures, strong acids and alkalis, and has wide chemical applicability. When used for gas filtration, it can achieve 100% retention of various phages, bacteria and particles above 0.02um.
PTFE microporous membrane has high filtration efficiency and can meet the filtration efficiency level requirements of sub-high efficiency, high efficiency and ultra high efficiency air filters.
