Amspec Select
Amspec Select is a higher purity grade of antimony trioxide compared to Amspec KR antimony trioxide. Amspec Select can be used in flame retardant applications where lead levels are of concern, like in Europe to meet the requirements of the RoHS Directive. The Select grade is also used as a catalyst in PET production.
