Technology Development

Inspired by the hair structure of Saharan silver ants, the R&D team of i2Cool has successfully transformed cutting-edge research prototypes into large-scale commercial products after 7 years of in-depth research. By optimizing material particles and blending high-molecular polymers with inorganic particulates, i2Cool has developed low-cost solutions with optimal optical and thermal properties, boasting an impressive 95% solar reflectivity and mid-infrared emissivity. This breakthrough surpasses the reflectivity limit of previous thermal insulation coatings.
