Nano grain size tungsten trioxide may be applied for manufacturing thermal insulation paper due to its thermal insulation performance. This kind of paper is excellent for use as die cut gaskets and seals as it resist high temperature, acid, alkali and other corrosive substances. And it is available in a variety of widths and thickness for your specific application.
Tungsten trioxide also has wetting property. For example, the superhydrophobic coating with photochromism and mechanical stability can be prepared using tungsten trioxide as raw material. First, micron tungsten trioxide particles of uniform size were obtained by acid precipitation, and modified with octadecyltrichlorosilane to obtain superhydrophobic tungsten trioxide particles. Then, the adhesion between the substrate and the coating layer is increased by the epoxy resin, and the obtained superhydrophobic tungsten trioxide particles are coated on the glass substrate to obtain a contact angle of about 155° and a roll angle of about 3.5° super hydrophobic coating.
