1. High temperature resistance. The standard waterproof and breathable membrane is made of two layers of non-woven fabrics and a layer of polymer brea

1 microporous membrane In a microporous membrane, the size of the micropores is 0.1 to 50 μm, which determines that only air or water vapor can pas

The production processes of waterproof and breathable membranes are mainly divided into two categories: flash evaporation method and stretching method

For waterproof and breathable membranes, different manufacturers have different installation instructions. Some instructions are relatively simple and

Material: The material of the waterproof and breathable plug should have waterproof, dustproof, corrosion resistance and other properties to ensure it

Both waterproof breathable membranes and waterproof breathable oleophobic membranes are important waterproof protection products. While keeping the in

Material quality: The material quality of the waterproof sound-permeable membrane has a decisive impact on its service life. High-quality materials ge

First of all, the design of the porous structure can scatter and refract sound when it propagates inside the sound-transmitting membrane, thereby achi

Stretching method: First, the polymer film is heated, then plastically deformed under the action of stretching force, and finally rapidly cooled and f

Biaxial stretching method: When polytetrafluoroethylene (PTFE) is rapidly stretched, it becomes a strong, waterproof, breathable microporous material,

The microporous structure of the waterproof and breathable membrane can balance internal and external pressures, which mainly depends on the size and

Material selection: Choose materials with excellent mechanical properties and stability, such as certain polymer materials, which have high tensile st
