Description
Ammonium thiocyanate (CAS 1762-95-4), also known as ammonium rhodanate, ammonium rhodanide, and ammonium sulfocyanide, is an inorganic salt supplied as a colorless hygroscopic solid. It carries no E-code designation and is registered under EC number 217-175-6.
In textile and leather processing, ammonium thiocyanate functions as a flame retardant by releasing nitrogen- and sulfur-containing decomposition gases that interrupt combustion chemistry at the flame front. It is also applied in building and construction materials and polymer formulations where halogen-free flame retardancy is required by specification.
Ammonium thiocyanate is available in technical and industrial grades and falls under REACH registration requirements for supply within the EU. It is classified under HS code 28380000 for customs purposes. Packaging formats typically include 25 kg bags or bulk quantities depending on volume requirements.
