Here, zinc borate works with antimony trioxide and alumina trihydrate. 
Zinc borate also has anti-drip properties.  
Halogen-free systems: Zinc borate works with alumina trihydrate, magnesium hydroxide, red phosphorus or ammonium polyphosphate to do the same. 
As the plastics burn, a porous boron ceramic is formed, protecting the layers beneath. 
Halogen-free systems show better flame retardant properties.

Production Methods
Zinc borate (2ZnO·3B2O3·3.5H2O) in general is produced with the reaction between zinc oxide and boric acid. 
Boric acid is solved in water between temperatures 95ºC and 98ºC and zinc oxide and seed crystal of 2ZnO·3B2O3·3.5H2O is added to this solution at a certain stoichiometric ratio. 
The reaction continues for a while by mixing and the zinc borate formed is filtered, dried and ground.
The boric acid solution is fed to the system as reflux.
