DBDPE is a widely used brominated flame retardant with high bromine content and thermal stability. It is mainly used in thermoplastics, elastomers, and thermosets for fire-safe applications. DBDPE is a popular alternative to Deca-BDE with a similar structure but improved environmental profile.

Q1: Is DBDPE a drop-in replacement for Deca-BDE?
Yes, in many applications it performs similarly and is more environmentally acceptable.
Q2: Can DBDPE be used in halogen-free systems?
No. It is a brominated (halogenated) flame retardant. For halogen-free options, consider APP or MCA.
Q3: Is DBDPE suitable for high-temperature processing?
Yes. It is thermally stable up to 400 °C.
