ZINC BORATE 2335 (2ZnO·3B2O3·3.5H2O)
CAS No. 1332-07-6
Product Features:
It is white and nonpoisonous powder. It can be dissolved easily in hydrochloric acid, sulfuric acid, dimethyl sulfoxide etc. but not in water, ethyl alcohol, benzene, acetone etc. It has good dispersibility and stability property. It can be used as flame retardant, meanwhile it can abate smoke. When it is used with Antimony Trioxide, Chlorinated Paraffin -70 together, the effectiveness of flame retardant will be better than ever.
