Sodium antimonate,as flame retardant,SM-02

Sodium meta-antimonate could be used for engineering plastics(PET/PBT) to improve their high performance, as high-resistance fla

   Engineering plastics, which require high heat resistance, may be affected in their material features by depolymerization caused through adding antimony trioxide to the plastics. Our special new type, SM-02, penta-valent antimonate, provides engineering plastics with flame retardance without adversely affecting the material features of the original plastics by retaining their original heat and hydrolysis resistance. Although high crystal water and coarse particle size are a common feature of sodium antimonate, our special particle size has led to our success in the production of non-water and fine type SM-02 by eliminating water that causes hydrolysis and producing a fine particle size. The refractive index of this grade is similar to many kind of plastics, allowing the original transparency and clear coloring of the plastics to be closely maintained making it a better alternative to antimony trioxide.
