BDP is a halogen-free flame retardant that belongs to the family of oligomeric phosphate esters. It is based on bisphenol A bis-diphenyl phosphate as the monomer.
The use of BDP is particularly suited for engineering resin alloys like PC/ABS and PPO-PPE/HIPS used in electric and electronic applications. Depending on the fire safety code aimed at, some 8 to 18phr of BDP are commonly used. In contrast with other brominated flame retardants, BDP does not require the use of a synergist (typically Antimony Oxide), which constitutes an advantage in terms of the recyclability of the goods.
In addition, its low volatility and thermal stability lie well within the processing condions of most engineering thermoplastic resins. BDP, due to its marked flowability, allows the production of thin wall moldings.
Finally, its resistance toward hydrolysis compared to other flame retardants impart the final well with enhanced cracking and “juicing” properties.
