Ammonium thiocyanate

Ammonium thiocyanate (CAS 1762-95-4), also known commercially as Trans-aid and by the abbreviation NH4SCN, is an inorganic salt sourced for its flame retardant properties.

Where is Ammonium thiocyanate used?

• Wet-process industries: reactive auxiliary delivering nitrogen- and sulfur-based chemistry that interrupts combustion pathways in polymer and fiber systems
• Textile processing: dyeing auxiliary and anti-felting agent for wool, improving fiber receptivity and dimensional stability
• Leather and paper: processing aid to modify surface characteristics and control shrinkage during treatment
• Plastics and polymer formulations: flame retardant performance in halogen-free systems
• Construction adhesives and cementitious formulations: controlled set modification and flame retardancy
• It is a white crystalline solid, typically in powder or granular form.

Commercial specifications

• Purity levels commonly range from 97% to 99%.
• Technical grade is the standard offering for industrial applications with high purity levels.
• Packaged in moisture-resistant bags or drums given its hygroscopic behavior in standard warehouse storage conditions.
