Product Description
GOYENCHEM-SIPM is a functional sulfonated aromatic monomer
designed for the modification of polyester (PET), copolyester, and specialty polymer systems.
By introducing sulfonic acid functional groups into the polymer backbone,
SIPM significantly improves:
- dyeability of polyester fibers
- hydrophilicity and moisture absorption
- antistatic performance
- dispersion and compatibility in aqueous systems
It is widely used in the production of cationic dyeable polyester (CDP) and advanced textile materials.
Core Value: Dyeable Polyester + Hydrophilicity + Functional Modification
Designed for polyester manufacturers seeking enhanced dyeability and functional polymer performance.
✔ enables cationic dyeable polyester (CDP)
