Waterproof and moisture-permeable means that water does not invade the fabric under corresponding pressure, but the sweat vapor emitted by the human body itself can diffuse or be transmitted to the outside through the fabric and does not accumulate and condense on the body surface. Between it and the fabric, it will not make the human body feel stuffy. The waterproofing and moisture permeability of ptfeWaterproof Breathable Membrane depends on the structure and surface wetting properties of the film. The morphological structure of the film has a great influence on the waterproof and moisture permeable performance.
The real waterproof and breathable membrane is not compounded with glue, so its temperature resistance is -40,100 degrees (CE standard, 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 a thin waterproof and breathable membrane is at least 1.5 meters, and that of a thick waterproof and breathable membrane is at least 2 meters.
ptfeWaterproof breathable membraneThe manufacturer’s polytetrafluoroethylene microporous membrane is polymerized by tetrafluoroethylene Polymer compounds are obtained through biaxial stretching and are one of the materials with good corrosion resistance in the world today. Except for a few chemicals such as chlorine trifluoride and liquid chlorine, it can withstand any other chemical reaction and is insoluble in strong acids, strong alkali, organic The solution does not change in boiling nitrohydrochloric acid. The temperature resistance range is -195℃～250℃, and the long-term use temperature is -100℃～250℃.
It is a ptfewaterproof and breathable membrane material manufacturer that specializes in R&D, production and sales. Our company is different from other manufacturers. Our company can according to the user’s requirements. By optimizing the combination of key technical parameters such as speed ratio, pressure ratio, and operating temperature, the air permeability, thickness, and void ratio can be adjusted online according to the ratio and pore-forming medium to meet your different requirements. Interested parties can enter the store for consultation.
