i2Cool

Shenzhen, China – September 29, 2026 -- i2Cool has expanded its passive radiative cooling fabric line with two electricity-free products, i2Umbrella Fabric-Hyber and i2Tarpaulin, that lower surface temperatures without power or refrigerants.

New umbrella fabric cuts ambient temperature by 5.2°C without electricity

i2Umbrella Fabric-Hyber, engineered for umbrellas, patio shades and outdoor canopies, achieves solar reflectivity of up to 76% and mid-infrared emissivity of up to 96%. In controlled outdoor testing, the fabric produced internal temperatures 5.2°C cooler than unshaded areas and 2.4°C cooler than conventional silver-coated sun-protection fabrics. The material also blocks 99% of UV radiation and offers full blackout capability with high water repellency.

Shenzhen – September 11, 2026 -- i2Cool Shenzhen Limited has closed a Series B financing round worth tens of millions of yuan, equivalent to several million US dollars, backed by Shenzhen TopoScend Capital Co., Ltd., with Linglu Capital acting as exclusive financial adviser.

The company, which develops electricity-free passive radiative cooling materials, will use the proceeds to build standardized nanoparticle production lines, advance core technology, recruit key talent, and expand commercially in priority global markets.
