Cooling Film for Building

Tech & Electronics;

It is necessary to develop a cooling film for buildings, which can be used on the roofs of grain depots, data centers, cold chain storage, etc., combined with waterproof functions, to realize the integration of cooling and waterproofing of building exposed systems.

Technical Standard：

➣The reflectance of sunlight exceeds 95%;

➣ Near-infrared emissivity exceeds 90%. On the other hand, the radiation selectivity of the atmospheric window with a wavelength of 8-13um is high, and the near-infrared reflectance in this band exceeds 95%. Throwing energy into outer space has an inhibitory effect on spontaneous radiation beyond this spectral band;

➣Under the light of 1000W/㎡, the temperature difference between the inner and outer surfaces of the film exceeds 20°C;

➣The surface of the film roll has a self-cleaning function, and the pollution does not exceed 10%;

➣The cold film adopts polyolefin base material, which can be combined with polyolefin waterproof membrane or can be integrated into the co-extrusion production process of waterproof membrane. The waterproof performance index can refer to GB27789-2011 polyolefin waterproof membrane.
