However, poor quality PTFE waterproof and breathable membranes or even fake breathable membranes are generally made of materials that are compounded with various glues, such as hot melt composite glue and spray glue, which are more common. The waterproof and breathable membrane made of this material has poor temperature resistance. Temperatures slightly higher than normal will cause the glue to melt and crack, causing delamination.
