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. -
