Antimony Trioxide (ATO) as a Flame Retardant Synergist: Ratios and Best Practice
How to Achieve a UL 94 V-0 Rating with Brominated Flame Retardants
What is a flame retardant masterbatch?
A masterbatch is a concentrate of flame retardant and synergist pre-dispersed in a carrier resin. Instead of handling fine powders, compounders meter pellets, which improves accuracy and plant hygiene.
Key benefits
- Better dispersion and more consistent flame retardancy
- No airborne dust, improving workplace safety
- Accurate let-down ratios on standard pellet feeders
- Pre-balanced bromine-to-antimony ratio in a single product
When powder still wins
For very high loadings or when a compounder already runs gravimetric powder feeders, direct powder addition can be more economical. Masterbatch shines for injection moulders adding flame retardancy at the press without a compounding step.
Frequently Asked Questions
What is flame retardant masterbatch?
It is a pelletised concentrate of flame retardant and synergist in a carrier resin, used to dose flame retardancy cleanly and accurately.
Is masterbatch better than powder?
Masterbatch gives better dispersion, dust control and dosing accuracy. Powder can be cheaper at very high loadings or where gravimetric feeders are already in use.
