William Blythe manufactures copper (I) iodide to a rigorous standard, eliminating impurities that can lead to severe discolouration. Copper iodide has poor solubility in water and limited solubility in 50w% potassium iodide solutions. As a result, it can be used as a carrier of iodine where non-water solubility is required in biochemical pathways. William Blythe’s copper (I) iodide is also used in conjunction with potassium iodide to counteract the destructive effects of heat and light on polyamides, preventing discolouration and preserving the mechanical properties of polyamides (e.g. Nylon 6 and Nylon 66) in technical and engineering applications.
