Blue tungsten oxide may be used to prepare a new heat insulation masterbatch, which is blue-black in color and is of high transparency when it is prepared into a thermal insulating film. It is reported that such masterbatch can reflect the infrared heat directly, and avoid the infrared heat from concentrating on the surface of glass. Under lighting condition, the heat insulation fabric made of such brushed wire has a surface temperature lower than that of ordinary fabric.

So, what are the characteristics of the new thermal insulation masterbatch of blue tungsten oxide nanoparticles? Good spinnability, long wires and short wires are available; infrared reflectivity of 30-50%, obvious heat insulation effect; strong weather resistance, no fading under long-time illumination, no attenuation of performance; safe and non-toxic, no pollution to the environment. What are the applications? For the development of reflective heat insulation fibers; for parasols, sunshades, curtains and summer clothing such as shirts, underwear, T-shirts, etc. How to use? It is recommended to add more than 5% by weight and blend with the brushed grade common section. Suitable for a variety of substrates, such as PET, PP, PA, PA66 and so on.
