Q: Can zinc borate produce a synergistic effect with halogen-free flame retardants such as APP, ATH, and MDH?
A: To be direct, yes, and it can produce significant synergistic effects with many halogen-free flame retardants. We can supply the flame retardants mentioned in the question, and we can also customize formulations for you. For example, when APP is combined with zinc borate, it can improve the char layer strength and stability, and improve the UL94 rating of the system; when combined with ATH and MDH, the boron and zinc in the structure can further enhance the smoke suppression performance, making the material burn cleaner.
Q: How much Zinc Borate Hydrate should be added to the polymer when flame retardant?
A: 5%–15%. However, a more specific value needs to be determined after assessing the material system, whether it synergizes with other flame retardants, and the flame retardant rating requirements. In short, it should be evenly dispersed when added.
Q: How to determine whether to choose hydrated or anhydrous zinc borate?
A: Consider the processing temperature of your material system and the flame retardant target before making a choice. If the material processing temperature is below 280℃ and you want better smoke suppression performance, we recommend choosing a hydrated type; however, if you do not need or even want to release moisture during processing, and the processing temperature is higher, then anhydrous is definitely more suitable.
