Nantong Kangda Composite Material Co., Ltd. was established in 2004, and registered the trademark "Kedebang". It has been specialized in producing waterproof and breathable films for decades pin Overseas and all over the country, there are also small workshops on the market to imitate the production. The price is low. Although the naked eye looks similar, the raw materials and processes are very different from our factory, which directly affects the future performance and service life of the product. We hope Everbright customers will recognize our brand "Kedebang" when they buy it, and not blindly covet the present cheap, which will affect the long-term use in the future!

Working principle of waterproof breathable membrane:
In the state of water vapor, the water particles are very small. According to the principle of capillary movement, they can smoothly penetrate to the capillary to the other side, thus causing the phenomenon of vapor permeability. When the water vapor condenses into water droplets, the particles become larger. Due to the surface tension of the water droplets (the water molecules "pull against each other"), the water molecules can not be separated from the water droplets and permeate to the other side smoothly, which prevents the water infiltration and makes the vapor permeable membrane waterproof.
Process of waterproof breathable film:
1. Advanced production process: the waterproof breathable film adopts advanced hot pressing composite production process, which belongs to the domestic * * *, no glue and no solvent composite, all advanced.
2. Excellent anti-aging performance: During the construction process, the waterproof breathable film will certainly withstand the dual test of strong ultraviolet and high temperature. Even after the pavement is completed, it will also be exposed to and exchanged with cold and hot air for a long time. Therefore, good anti-aging performance is the necessary condition and quality guarantee for the product. The waterproof and breathable film has passed the test of the National Building Materials Test Center. The product has been tested by 500 hours of strong ultraviolet radiation and 2160 hours of 100 ℃ high temperature, ensuring the durability and service life of the "Kodebong" waterproof and breathable film.
