Flame Retardants for Polyamide (Nylon) and PBT
Brominated Flame Retardants in Textiles and Back-Coatings
Efficiency and loading
Brominated flame retardants are highly efficient, so they work at lower loadings, which preserves mechanical properties and keeps cost down. Halogen-free systems such as metal hydroxides often need 50-60% loading to perform.
Where halogen-free fits
Halogen-free is chosen where low smoke and corrosivity are mandated, for example in rail and tunnel cable. The trade-off is higher loading, heavier parts and sometimes reduced mechanical performance.
Making the decision
If regulations or end-use specify low-smoke halogen-free, that path is clear. Otherwise brominated systems with antimony trioxide remain the most cost-effective route to high flame retardancy at low loading.
Frequently Asked Questions
Are brominated flame retardants more efficient?
Yes. Brominated flame retardants work at much lower loadings than halogen-free mineral systems, which helps preserve mechanical properties and cost.
When should I choose halogen-free?
Choose halogen-free when low smoke and low corrosivity are required by regulation or application, such as rail and tunnel cabling.
