Introduction:
Zinc Borate is one environmental-friendly halogen -free f lame retardant.There are some formulations of X ZnO. YB2O3.ZH2O,in which Zinc
Borate with 3 hydrate is called ZB-2 23 (2ZnO .2B2O3.3H2O). ZB-223 is an good flame retardant synergist and smoke suppressant in
polymers to partially replace Antimony Oxide,and can be used in certain applications as afterglow suppressant and antiarcing agent.Due to
its high Zinc content, ZB-223 is mainly recommended for PVC,and also have applications in polyolefins, polyurethanes, thermoplastic
elastomers and rubbers.
Package:
Zinc borate should be pack, transported, stored as normal chemical goods.
Standard package is 25kg/bag,500kg/bag,and can design package according to order.
