Frequently Asked Questions
What is BDDP?
BDDP is a brominated flame retardant (TBBPA bis(2,3-dibromopropyl ether)) suited to polyolefins and foams. Its bromine content is ~62%.
What is the CAS number and formula of BDDP?
BDDP has the CAS number 21850-44-2 and the chemical formula C21H24Br8O2.
What is BDDP used for?
BDDP is used for flame-retardant polypropylene and polyethylene articles and EPS/XPS insulation and packaging foams for construction.
How does BDDP work?
It works in the gas phase releasing bromine radicals and offers good compatibility and light stability in polyolefins. It is used with antimony trioxide as a synergist.
Which materials is BDDP compatible with?
Polypropylene, polyethylene, expandable and extruded polystyrene (EPS/XPS) and foams.
Is BDDP brominated or halogen-free / is it regulatory compliant?
BDDP is a brominated flame retardant valued for good UV stability and low volatility in polyolefins. REACH/RoHS documents available on request.
What is the typical dosage or concentration of BDDP?
Typical loadings are ~10-20% with antimony trioxide synergist, depending on the resin and required rating.
How should BDDP be stored and handled?
Store in a cool, dry, well-ventilated place away from heat, ignition sources and direct sunlight, in sealed original packaging and away from strong oxidisers. Refer to the SDS for full handling guidance.
