BDP is a non-halogen flame retardant with good low volatility and thermal stability in production applications, meeting the processing requirements of most plastic products. With high hydrolytic stability, heat resistance, high insulation property.

BDP is commonly used as a flame retardant for modified PPE (PPO), HIPS, PC, ABS, HIPS and other engineering plastics, synthetic fiber.
For example, it is suitable for engineering plastic alloy, production and manufacture of flame retardant PC/ABS alloy, HIPS/PPO alloy. Polycarbonate (PC), ABS, modified PPE. Polystyrene (PS), Polyurethane, Epoxy resin, textile, etc.
