Calcium bromide and flame retardants
Bromine is one of the most effective elements for stopping a fire. Calcium bromide is a handleable, water-soluble source of bromide for flame retardant chemistry.

How bromine stops a flame
A flame is a chain reaction carried by reactive radicals, mainly H• and OH•. When a bromine-containing material heats up it releases bromine atoms and hydrogen bromide, which capture those radicals and turn them into much less reactive species. With the chain broken, the flame loses energy and goes out.
Where calcium bromide fits
Most commercial flame retardants are organic brominated compounds, not calcium bromide itself. CaBr₂ is a convenient inorganic bromide source for specialty syntheses and some water-based treatment formulations.
Straight talk. If you need a specific retardant, tell us the target compound or formulation. We will say plainly whether calcium bromide fits your process.
What to check before you buy
- Purity, moisture and chloride content for your process.
- Whether your market restricts certain brominated flame retardants.
- Safety data sheet and handling requirements.
- Packing form: liquid or powder.
Frequently asked questions
Is calcium bromide itself a flame retardant?
It can play a role in some formulations, but most flame retardants are organic brominated compounds made from bromine chemistry. CaBr₂ is mainly a bromide source.
Are brominated flame retardants regulated?
Rules vary by region and by compound. Check the regulations that apply to your product and market.
