Antimony glycol is the latest product of antimony polyester polycondensation catalyst, and it is a substitute for antimony trioxide and antimony acetate catalysts. Since ethylene glycol antimony does not bring into acetate, zero-valent antimony and high-valent antimony in the polycondensation reaction, the produced polyester product has the characteristics of excellent color and luster, high thermal degradation stability, good spinnability, etc., and eliminates the need for acetic acid. Root corrosion of equipment.
Advantages of Chenzhou ethylene glycol antimony:
The physical index of ethylene glycol antimony is better than similar dry ethylene glycol antimony, with high L value and low B value.
Ethylene glycol antimony can be fully dissolved in 20 minutes at 70℃.

In addition to reducing energy consumption, the washing and drying procedures in the traditional production process are reduced to prevent the reduction reaction of ethylene glycol and antimony and the entry of other substances.
Using the export EU standard dangerous goods packaging grade, the inner bag is packed with vacuum aluminum-plastic, which can effectively ensure the product quality.
Hunan Chenzhou Mining Co., Ltd. has abundant reserves of antimony ore resources in the country, and the supply capacity is our absolute advantage.
