Yellow Tungsten Oxide Thermal Cloth 228

Yellow tungsten oxide thermal cloth is made adding yellow tungsten oxide (tungsten trioxide/WO3) master particles as warm particles. The light-absorbing molecules in the WO3 masterbatch absorb infrared rays, and the molecular vibration is intensified, causing the temperature to rise, thereby converting light energy into heat energy. Under light conditions, the surface temperature of the prepared light-absorbing heating fabric with WO3 nanoparticles is significantly higher than that of ordinary fabrics, so as to achieve a warming effect and help you fight…
