Flame Retardants Used Ultrafine Nano Antimony III oxide Powder Sb2O3

Product Description


Specification of antimony trioxide nano powder:


Paritcle size: 20-30nm

Purity: 99.5%

Color: white


Application of antimony trioxide nano powder:
1. Impact of Nano-Sb2O3 for PVC cable oxygen index greater than micron Sb2O3, when the oxygen index of 35%, the use of nano-Sb2O3 than micron add 20% reduction in the number of copies.

2. Antimony trioxide is used more often in PVC, flame retardant better a flame retardant synergist, Sb2O3 with halogen, phosphorus and nitrogen-based flame retardant synergists, to achieve good flame effect.

3. Wire and cable is used to transmit power, the transmission of information and implementation of a large class of energy conversion cable electrical products, its irreplaceable in economic activity and social life.

4. Due to the small size of nanoscale Sb2O3, in the stretching process can be moved together with the sticky adhesive material of the matrix particles is preferably produced by a drag effect to increase the toughness of the material.

5. The specific surface area of nano-sized antimony trioxide than the micron level increases by about 140 times, which produces liquid and solid particles of antimony trichloride surface effect can be further reduced flame energy.
