WO3 may be used to prepare a type of environmentally friendly thermal insulation masterbatch. The used WO3 powder is nano particle size tungsten trioxide, and the obtained masterbatch is a new inorganic nano-modified masterbatch, which not only has non-polluting property, but also has the characteristics of high transparency, high heat insulation and high UV resistance. In addition, the obtained nanoparticles have excellent uniformity, dispersibility and stability. And all these properties have reached a relatively advanced level so that the quality…
