application

Zinc borate is mainly used as a flame retardant for plastic and cellulose fibers, paper, rubber and textiles. It is also used in paints, adhesives and pigments. As a flame retardant, it can replace antimony trioxide as a synergist for halogen and halogen-free systems. It is an anti-drip and scorch booster that suppresses afterglow. In electrical insulator plastics, it suppresses arcing and tracking.
