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. .
It is a manufacturer of polytetrafluoroethylene microporous membranes that specializes in R&D, production and sales.
