Products Description
Antimony Triacetate is an organic antimony compound with the chemical formula Sb(CH₃CO₂)₃. It appears as an off-white powder and serves as a highly efficient, low trace-metal catalyst. Compared with traditional antimony trioxide (Sb₂O₃), it offers higher catalytic activity, faster incorporation into the monomer/polymer chain, and reduced antimony usage, enabling lower catalyst loadings and shorter reaction times.
