Absorbs IR, Chemical Resistant, Electrically Conductive, Excellent Transparency Properties, Good Chemical Stability, Good Electrical Properties, Heat Resistance, Infra Red Absorbing, Transparency; Indium tin oxide (ITO) has been known for a long time for its use as a transparent conductive oxide in electronic applications. Everyone who uses a touch screen most likely has indium tin oxide under their fingertips. Indium tin oxide is a vital component of modern electronics due to its unique features.; Indium tin oxide exists in several modifications depending on the manufacturing process, which can be identified not only by a varying composition in respect to the indium to tin ratio, but also by its color. The most chemically stable form of ITO has a yellow color, whereas the reduced form is a blue colored powder. ITO with a greenish color is a mixed form generated by high temperature processes.

- HIGHLIGHTS
Using a proprietary process, ITO is converted into its blue form, which significantly increases the ability of the ITO to absorb IR light without compromising the transparency in the visible range.; Irasorb BITO and BITOM40 are powders which can be easily dispersed in polymers during the extrusion or injection molding process. They deagglomerate readily into nanoscale particles to enable transparent polymer films, sheets and plates to be formed.; Although the BITO powder is of blue color it has only very little influence on the final color of polymers, coatings or inks.; BITO has excellent IR absorbing properties, with its maximum IR absorption reached at 1100 nm. Low quantities of BITO are necessary to achieve high NIR absorption rates. In addition, BITO has the highest transparency of all IR absorbing materials.; Keeling & Walker offers indium tin oxides in both powder form and as nanoscale dispersions in water, plasticiser and other solvents to facilitate the use of the ITO and to ease the formulation of inks and coatings.
