How to identify the quality of waterproof and breathable membranes on the market

First, we need to understand the basic characteristics of waterproof and breathable membranes. Waterproof and breathable membranes are mainly made of polyester, polyurethane, polyvinyl chloride and other materials, and have the characteristics of waterproof, breathable, wear-resistant and weather-resistant. A good waterproof and breathable membrane should have excellent waterproof performance, which can effectively prevent moisture penetration; at the same time, it should have good breathability and can discharge moisture generated by the human body to maintain a comfortable experience; in addition, the wear resistance of the waterproof breathable membrane and weather resistance also need to be guaranteed.

Secondly, we can initially judge the quality of the waterproof and breathable membrane by observing its appearance. A good waterproof and breathable membrane usually has a flat and smooth surface without obvious wrinkles, pores and color differences; the membrane material should be uniform, strong and not easy to tear. In addition, the material and process of the film can also be judged by observing the color of the film. Generally speaking, films with uniform and bright colors are of better quality.

In addition to appearance, we can also judge the quality of waterproof and breathable membrane by its feel. A good waterproof and breathable membrane should be soft to the touch and have a certain degree of elasticity; at the same time, you should also pay attention to the thickness of the membrane. A membrane that is too thin or too thick may affect its service life and performance.

In addition, we can also judge the quality of waterproof breathable membranes by testing their breathability. Breathability is one of the important indicators to measure the quality of waterproof breathable membrane, and it can be tested using professional equipment such as gas permeability meter. A good waterproof and breathable membrane should have high breathability, which can ensure waterproofing while draining moisture generated by the human body and maintaining good breathability.
Finally, we can understand the manufacturer and relevant certification status of the waterproof breathable membrane to judge its quality. Well-known brands and reputable manufacturers usually strictly control product quality and generally have various certifications and testing reports; at the same time, you can also learn about the quality of various brands on the market by understanding the use experience of other consumers. .
