RoHS and REACH Compliance for Brominated Flame Retardants
Flame Retardants for EPS and XPS Insulation Foam
The processing problem
Engineering plastics process at 260-320 C. A flame retardant that decomposes early releases bromine prematurely, causing corrosion, discolouration and lost performance.
Stable choices
DBDPE (stable to about 350 C) and BT-93W (above 400 C) are selected for high-temperature polymers. Lower-stability additives are limited to polyolefins processed at milder temperatures.
Practical tips
Keep residence time short, control melt temperature, and use acid scavengers where needed to protect both the polymer and the equipment.
Frequently Asked Questions
Which flame retardants are most thermally stable?
BT-93W (stable above 400 C) and DBDPE (around 350 C) are among the most thermally stable brominated flame retardants.
What happens if a flame retardant degrades during processing?
Premature decomposition releases bromine, which can cause corrosion, discolouration and reduced flame retardancy.
