Applications of Zinc Borate Powder
Zinc borate is primarily used as a flame retardant in plastics and cellulose fibers, paper, rubbers, and textiles. It is also used in paints, adhesives, and pigments. As a flame retardant, it can replace antimony (III) oxide as a synergist in both halogen-based and halogen-free systems. It is an anti-dripping and char-promoting agent and suppresses the afterglow. In electrical insulator plastics, it suppresses arcing and tracking.

Zinc Borate Powder FAQs
Q1: How is Zinc Borate Produced?
Zinc borate is typically produced by reacting zinc oxide with boric acid in an aqueous solution. The reaction results in the precipitation of zinc borate, which is then filtered, washed, and dried.
Q2: What is the Environmental Impact of Zinc borate?
Zinc borate is considered to have a relatively low environmental impact compared to some other flame retardants. However, it is essential to handle and dispose of it properly to minimize any potential environmental risks.
Q3: What are the alternatives to Zinc Borate?
While zinc borate is effective, other flame retardants and smoke suppressants include aluminum trihydrate, magnesium hydroxide, and various organic phosphorus compounds. The choice of additive depends on the specific requirements and properties needed for the end product.
