Stearylamine (CAS 124-30-1) is a primary fatty amine derived from natural fatty acids that appears as white prills and serves as a functional intermediate in the production of cationic surfactants, softeners and emulsifying agents, and as an internal lubricant and mold release agent in polymer processing. With a 98% min assay , this chemical provides excellent surface-active properties and substantive behavior on various substrates. It is highly valued for its hydrophobic characteristics and ability to modify surface tension in industrial fluids. It ensures superior dispersion of additives and improves the processability of rubber and plastic compounds.
