Xin gourmet products according to customer requirements and provide the related testing equipment and a complete set of independent research and development plan and related equipment. We hope to provide our customers with high quality products through high quality service, continuous innovation and professional technology.

The development of waterproof breathable film is also a gradual process. From the original waterproof adhesive to meet the waterproof requirements of shoes, clothing and tents, to PU film with stable water resistance but not perfect, and then on the basis of PU film to improve the development of TPU film until the current waterproof and breathable film.

Material structure of waterproof and breathable film:
Waterproof breathable film has the functions of waterproof and breathable, heat preservation and heat insulation, the realization of these functions is determined by the structure material fabric of waterproof breathable film.

Principle of construction: waterproof and breathable film is composed of polymer material + polyolefin microporous film + polymer material by hot pressing composite, the technology is domestic first, international advanced. Polyolefin microporous membrane permeability is excellent, durable products, long service life.

Polyolefin microporous membrane is not only anti-corrosion and acid and alkali resistance, but also has excellent elongation properties. It can bounce back quickly after piercing nails to increase the sealing performance. Its waterproof and breathable properties can make the water vapor in the indoor or thermal insulation layer leak out, and when the water vapor condenses and forms water droplets, the water droplets will be blocked outside the breathable film. Thus ensuring the performance of the interior and building, but also heat insulation. It is a new high-tech energy saving and environmental protection material.

Its working principle is breathable working principle can be divided into two kinds of, microporous and hydrophilic groups, due to the minimum of about 20 microns in diameter, water droplets and the water vapor molecules just 0.0004 microns in diameter, the diameter of a huge difference, principle of water vapor can spread through the microporous membrane, the surface tension of liquid water or water because of its role, make water molecules cannot pass, It also prevents the penetration of water, so that the breathable film has a waterproof function.
