Dimethyl 5-Sulfoisophthalate Sodium Salt (SIPM)
High-purity sulfonate functional monomer used to produce cationic dyeable polyester, functional polyester and specialty film materials.
High-purity sulfonate monomer for cationic dyeable polyester and functional polyester systems
SIPM is a high-purity sulfonate monomer for cationic dyeable polyester and other functional polyester systems. It introduces sulfonate functionality into polyester chains, improving affinity for cationic dyes and supporting bright, durable coloration. SIPM is suitable for textile fibers, specialty polyester films, packaging materials and fine chemical polymer modification.
