Production: WOP-P100 ¡¾Introduction¡¿ WOP-P100 is a blue powder which is made from highly purified WO3. Pure WO3 is sintered at a high temperature, doped with metal oxide and then extracted by flow dispersion to get the product. The physical and chemical properties of as prepared blue WO3 are different from yellow or green WO3. Blue WO3 shows excellent optical characteristics, such as high VLT value, good NIR cutoff and excellent ability to absorb UV rays. It has high heat insulation ratio in NIR zone, especially when IR wavelength is in the scope of 800nm to 1000nm and it also possesses high UV absorption ability when light wavelength is less than 380nm. And its optical properties are similar with GTO throughout the total wavelength band. ¡¾Characteristics¡¿ Physical and Chemical Properties Item Data & Results Appearance Blue powder Particle size 40nm Specific surface area (BET) 30-50m2/g Purity No less than 99.9% SG 1.62g/m2 Ingredient WO3 ¡¾Application Field¡¿ Heat insulation media for solar film Transparent heat insulation coating Heat insulation window Transparent anti-UV coating Warmth retention fiber Heat absorption material ¡¾Instruction¡¿ The product can be applied directly or converted into nano solution such as coating or adhesive. ¡¾Storage¡¿ The product must be kept in a cool place.
