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.

Sodium Antimonate (NaSbO3) is a kind of inorganic salt, and also called sodium metaantimonate. White powder with granular and equiaxed crystals. High temperature resistance, still does not decompose at 1000 ℃. Insoluble in cold water, hydrolyzed in hot water to form colloid.
Polyester Catalyst Grade Antimony trioxide(ATO)(Sb2O3) powder Minimum Pure 99.9%

Antimony(III) Oxide is the inorganic compound with the formula Sb2O3. Antimony Trioxide is an industrial chemical and also occurs naturally in the environment. It is the most important commercial compound of antimony. It is found in nature as the minerals valentinite and senarmontite. Antimony Trioxide is a chemical used in the manufacture of some polyethylene terephthalate (PET) plastic, which is used to make food and beverage containers. Antimony Trioxide is also added to some flame retardants to make them more effective in consumer products, including upholstered furniture, textiles, carpeting, plastics, and children’s products.
