i2Cool Shenzhen Limited (i2Cool)

Materials that cool by radiating heat

i2Cool's Particle+ platform uses functional nanoparticles and material engineering to reflect incoming solar energy and emit heat through the atmospheric infrared window. Unlike air conditioning, the cooling effect does not require electricity at the surface being cooled.

The company offers multiple material formats, including coatings and films, and works with manufacturers in applications such as buildings, vehicles, textiles and industrial products. Its technology page describes polymer sheets, ceramic materials and cooling pavement, illustrating how the underlying material system can be adapted to different surfaces and products.
