BDP, an oligomeric phosphate ester flame retardant, is designed for use in engineering resin application such as polyphenylene oxide alloys and PC/ABS. Because of its low volatility and high heat stability, this phosphorus flame retardant can tolerate high processing temperature required for many engineering resins.

Processing characteristics in a number of thermoplastics including ABS and HIPS that benefit high flow in thin wall moldings and other high-performance applications.

BDP is used at 8 to 15 phr to provide flame retardancy to a variety of resins .when used as a processing aid, 1 to 3 phr of BDP is added to thermoplastics for improving melt flow.
