High bromine content (≥77% w/w) delivering efficient flame inhibition in polymer matrices.
Excellent thermal stability, supporting processing temperatures up to 280°C without significant decomposition.
Low volatility and minimal plate-out tendency during extrusion and injection molding.
Good compatibility with engineering thermoplastics including polybutylene terephthalate (PBT) and polyethylene terephthalate (PET).
Complies with UL 94 V-0 rating at appropriate loadings in PBT-based systems.
Flame-retarded polybutylene terephthalate (PBT) for automotive electrical connectors and housings.
Enhanced fire safety in polyethylene terephthalate (PET) used for electronic component enclosures.
High-performance flame retardancy in glass-fiber-reinforced thermoplastics for industrial equipment.
UL-certified applications requiring stringent smoke and afterglow performance under glow-wire testing (GWT).
