Chemical Formula: ( 2ZnO .2B2O3 . 3H2O ) CAS NO: 1332-07-6 Grade/Item ( 2ZnO .2B2O3 . 3H2O ) Excellent grade First grade Whiteness 99 95 Surface water % ≤ 1 3 P article size , um 5-8 5-8 Pb, PPM < 10 20 Cd, PPM < 5 10 ZnO , % 44 .0-4 7 .0 B2O3, % 37 . 5 －4 0 .0 H2O(hydrate)， % 13.5－15.5 Fineness (Residue on 45um sieve ) ， % ≤ 0.1 Specific gravity, g/cm3 2. 83 Melting point ℃ 980 Temp. of dehydration ℃ > 20 0 Refractive index 1.58 Applications: Zinc Borate have some formulations of xZnO.yB2O3 . zH2O in which there is different crystal hydrate. ZB223 grade has 3 crystal hydrate its formulation , it has low dehydration temperature at 200 ℃ ,so the processing temperature is low.ZB 223 grade is one smoke suppressant, also can be used as an afterglow suppressant and antiarcing agent in certain applications. Due to its high Zinc content, ZB 223 is mainly used in EVA, PVC etc, and also has applications in polyolefin, polyurethanes, thermoplastic elastomers, rubbers etc. Transportation&Package: Standard package is 25kg/bag,40bags/pallet,18MT/20''container. Zinc borate should be stored with very good seal, and transported as normal chemical goods. |
