Nano-scale antimony trioxide has the characteristics of high purity, high whiteness, narrow particle size distribution, small average particle size, low impurity content, high proportion of cubic crystal form, and low tartaric acid insoluble matter.
(1) It is used as a high-efficiency catalyst in polyester polycondensation reaction, and has the characteristics of good solubility, uniform dispersion, good catalytic activity, and rapid polycondensation reaction.
(2) It is used as a flame retardant synergist in chemical fiber melt spinning, with long spinning cycle and not easy to break.
(3) As a flame retardant synergist, it is widely used in the rubber industry, which is convenient for extrusion molding and improves the physical and chemical properties of the tensile and impact strength of the material.
(4) It is used as a high-efficiency reaction raw material in other antimony compound production industries.
(5) It can also be used in electronic ceramics, epoxy resin, enamel, glass, medicine and other industries.
The net weight of each bag is 25KG, 300KG and 500KG.
