Zinc borate in a polymer is known to promote the formation of char.
Specialized borate compounds, such as zinc borates, are used as fire retardants and smoke suppressant additives in polymers, plastics, and rubber applications. 20 Mule Team® Borax Firebrake products, Firebrake 500 and Firebrake ZB, are designed as flame retardants for polymers. Although its applications are extensive and varied, Firebrake ZB, for example, is a multipurpose synergist in both halogen-containing and halogen-free polyolefin. It acts not only as a flame retardant and anti-arcing agent, but as a smoke and after glow suppressor and a promotor of char formation. As a fire-retardant synergist, the product completely or partially replaces antimony oxide in the final product. The applications for boron based fire retardant applications are numerous:
