DOPO has high thermal stability, oxidation resistance and excellent water resistance. It is a reactive and additive flame retardant. Due to the phosphorus carbon bond, the flame retardant performance of DOPO is better than ordinary phosphate ester

The flame retardant is suitable for glass fiber filled polyamide 66 halogen-free flame retardant. As a white powder, it developed a new hue of flame retardant GFR PA66 (polyamide 66 filled with glass fiber).
