Shenzhen’s i2Cool Unveils Electricity-Free Cooling Fabrics

The new product line applies the company's proprietary nanoparticle-based technology to flexible, weather-resistant materials. While standard sun-protection fabrics focus solely on blocking light, i2Cool’s textiles achieve high solar reflectivity—up to 85% for the heavy-duty i2Tarpaulin—while simultaneously releasing thermal energy through mid-infrared radiation. This mechanism effectively prevents the heat build-up common in traditional umbrellas and canopy structures.

Testing underscores the performance gap between these materials and standard silver-coated alternatives. In a controlled field trial, the umbrella fabric maintained temperatures 2.4°C lower than conventional options. On a larger scale, the i2Tarpaulin demonstrated significant utility in agricultural settings; a deployment in a Kashgar, Xinjiang greenhouse recorded peak internal temperature reductions of 8.3°C. This performance translated to a 28.7% cut in cooling energy costs, suggesting a viable path for thermal management in both commercial infrastructure and smart agriculture. With an operational lifespan exceeding a decade, the materials aim to bridge the gap between laboratory-grade radiative cooling and practical, large-scale industrial application.
