Ethylene Glycol Antimony
Ethylene glycol antimony is a new, high‑efficiency catalyst for polyester polycondensation. Compared with traditional catalysts (antimony trioxide, antimony acetate), it offers distinct core advantages:
Superior solubility and dispersibility
It exhibits significantly higher solubility in ethylene glycol and disperses uniformly. This effectively prevents catalyst agglomeration, ensures a stable reaction system, and minimizes dead zones.
Higher catalytic activity
With a high antimony content and strong catalytic activity, it notably accelerates polyester polycondensation, shortens reaction cycles, increases plant capacity and productivity, and reduces production costs.
Enhanced product quality
High purity prevents introduction of additional impurities into the reaction system. It improves the intrinsic quality of polyester chips, enhances spinnability, streamlines downstream spinning processes, and delivers fibers with superior strength and toughness.
Developed and customized by UrbanMines, ethylene glycol antimony features stable physicochemical properties, high catalytic efficiency, and significant quality improvement. It has become the preferred catalyst for polyester process upgrades and is suitable for all polyester polycondensation applications.
