Beyond its well-known function as a flame retardant synergist, Antimony Trioxide (Sb2O3) plays a pivotal role in the chemical industry as a catalyst, particularly in the production of Polyethylene Terephthalate (PET). NINGBO INNO PHARMCHEM CO.,LTD. sheds light on this critical application, underscoring the compound's versatility and contribution to modern material science.

PET is a ubiquitous polymer used in everything from beverage bottles and food packaging to synthetic fibers. The polymerization process to create PET involves a polycondensation reaction, and catalysts are essential to accelerate this process and achieve the desired molecular weight and properties. Antimony Trioxide, due to its specific chemical characteristics and thermal stability, is widely adopted as an esterification catalyst in PET manufacturing. Its use allows for efficient and controlled polymerization, resulting in high-quality PET resins.

The efficiency of antimony trioxide PET catalyst applications is well-documented. It facilitates the esterification and polycondensation stages, ensuring that the polymer chains grow to the optimal length required for various end-use applications. While Sb2O3 is highly effective, it is important to note that regulatory bodies often set limits on the migration of antimony into food and beverages from PET packaging. Manufacturers must adhere to these guidelines, and research continues into optimizing catalyst levels and exploring alternative catalysts.
