How to identify the quality of waterproof and breathable membranes

1. High temperature resistance.

The standard waterproof and breathable membrane is made of two layers of non-woven fabrics and a layer of polymer breathable membrane, rather than pasted with glue, so it can withstand temperatures up to -40,100 degrees (CE standard, ASTM standard). If the tested product cannot reach This standard indicates that the product is of inferior quality.

Second, breathability.

The standard air permeability of a standard waterproof breathable membrane is 1500g per square meter/24H. However, inferior products made of polyethylene or other materials cannot achieve this level of air permeability, or are not breathable at all, so it can be made based on this feature. filter.

3. Anti-aging detection.

Real waterproof and breathable membranes have anti-aging ability, because waterproof and breathable membranes are often used in outdoor environments, while fake and inferior products have no anti-aging ability and will be degraded quickly under ultraviolet irradiation, so we can do it outdoors. Irradiation testing to see if it has UV resistance.
