Our technology solves the heat problem caused by solar radiation. We use the radiative cooling technology on the film and coating which make them have 3 characteristics: high reflectivity, high emissivity, block sunlight. Then it can help people to save energy, reduce pollution and slow down global warming.kaisa has large-scale industrial application, core intellectual property rights and global patents layout. Our products are highly recognized by all clients and bring great value for them. The mainly products we have are refelctive film, transparent film, cooling coating and cooling fabric. The products can establish an efficient radiative heat tranfer channel between the Earth's surface temperature environment and outer surface by transmitting specific infrared rays and achieving radiative cooling. These products can be widely used in many fields such as huge build
