Zinc Borate 3.5H2O

1)Physical and Chemical Properties:

Molecular Formula: 2ZnO 3B2O3 3.5H2OMolecular Weight 434.68Appearance: white crystal powderRelative Density: 2.67Melting Point: 980Toxicity: <LD50> 1g/KgIndex of Refraction: 1.58

2)Usage:

Zinc Borate is widely used in producing polyolefine,rubber,hydroxybenzene resin,saturation insaturation resin, paper, fabric,carpet,paint,china,glaze, antiseptic and pesticide.Zinc Borate as upper-fine flame retardant, its character of smoke abatement is better than any other flame retardant, in producing polyolefine can replace antimony trioxide. Different model Zinc Borate has different usefulness.
