use
As a polyester catalyst, Sb2O3 is mainly used as the polycondensation catalyst of polyester.In addition,it is also used in the electronic ceramics, fluorescent powder and other industries.
Aa a kind of fire retardant,Sb2O3 is mainly used as a synergistic agent in the flame retard of plastics,resin,rubber,paint,fabrics,cooper clad laminate and other inflammables for improvement of fire retardance.
Packing
Sb2O3 is packed in plastic-paper bags in a unit net weight of 25kg,and stored in dry places with moisture protection.
