Use
Applied as anti-flaming agent which is unfit for Antimony trioxide,just like PET,because the Antimony trioxide will cause the PET depolymerize.The flame retardant property is also better than Antimony trioxide in many other plastic.
Packing
Is packed in plastic-paper bags in a unit net weight of 25kg;Should stored in dry places with moisture protection
