Antimony Ethylene Glycol is the latest product in the antimony-based polyester polymerization catalyst series. It serves as a replacement for antimony trioxide and antimony acetate catalysts. Since Antimony Ethylene Glycol does not introduce acetate ions, zero-valent antimony, or higher valence antimony in the polymerization reaction, the resulting polyester products exhibit excellent color, high thermal degradation stability, good spinnability, and eliminate corrosion issues caused by acetate ions on equipment.
Advantages of Chenzhou Brand Antimony Ethylene Glycol:
Superior Color Value:
Antimony Ethylene Glycol has better physical properties than similar drying-type Antimony Ethylene Glycol, with a higher L value and a lower B value.
High Solubility:
Antimony Ethylene Glycol fully dissolves in ethylene glycol at 70°C within 20 minutes.
High-Quality Raw Materials:
Self-sourced ore → Chenzhou brand antimony ingot → Chenzhou brand antimony trioxide → Chenzhou brand Antimony Ethylene Glycol
Leading Process:
In addition to reducing energy consumption, the process minimizes traditional washing and drying steps, preventing reduction reactions of Antimony Ethylene Glycol and contamination by other substances.
Premium Packaging:
Uses EU export standard hazardous material packaging, with vacuum aluminum-plastic inner packaging to effectively ensure product quality.
Strong Resource Advantage:
Hunan Chenzhou Mining Co., Ltd. holds abundant antimony ore reserves nationwide, giving us an absolute advantage in supply capacity.
