| Basic performance: |
| Samarium antimony pentoxide (Sb2O5) is an inorganic compound formed by antimony and oxygen. The chemical usually exists in the form of hydrate Sb2O5 · nH2O, and there is no definite evidence that anhydrous antimony pentoxide has been prepared. The oxidation state of antimony in this compound is +5. Antimony pentoxide is a weak oxidant and can react with reducing agents. |
| application: |
| Can be used as a high-efficiency flame retardant synergist for chemical fiber fabrics, plastics, paper, rubber and copper clad laminates, which can enhance the antistatic ability of plastics or other materials. This product is a general-purpose additive flame retardant, often used in combination with organochlorine and bromine flame retardants, and has a good synergistic effect. Used as flame retardant for polyethylene, polypropylene, polyvinyl chloride, polyester and other plastics. This product hydrosol can be uniformly and stably dispersed in the textile slurry, and can be dispersed in the fiber with extremely fine particles, which is suitable for spinning flame-retardant fibers. It can also be used for flame retardant finishing of fabrics. The fabrics treated with it have high washing fastness, and do not affect the color and luster of the fabrics. It is also used as antimony salt raw material glass decolorant, enamel and paint pigment, mordant, etc., and used in pharmaceutical and alcohol separation. Used in the manufacture of antimonate, antimony compounds and the pharmaceutical industry. It can also be used as metal passivating agent in petroleum refining industry. |
| Storage and transportation: |
| Store in a cool, ventilated warehouse. Keep away from fire and heat sources. Packaging is sealed. It should be stored separately from reducing agents, acids, and edible chemicals. The storage area should be equipped with suitable materials to contain spills. This product is non-dangerous, and it should be protected from moisture, rain and packaging damage during transportation. |
