DOPO derivatives ProFlame® P2024
CAS NO.: 1631149-46-6 Chemical Formula: C32H24O4P2 Other Name: DI-DOPO
P2024 is a novel DOPO derivatives flame retardant containing biphenyl and phenanthrene ring structures, with higher thermal stability and better chemical stability. The characteristics are high efficiency flame retardancy, low dosage, halogen-free and non corrosive, easy to use, and suitable for high processing temperatures. The hydrolysis stability and thermal stability are higher than those of general phosphate esters. P2024 has a higher phosphorus content than traditional phosphate flame retardants and an initial decomposition temperature above 350°C. It is suitable for engineering plastics that require high-temperature processing and certain general plastics. Due to the plasticizing effect of ordinary phosphate flame retardants and their significant impact on physical properties such as HDT, P2024 can be considered for halogen-free flame retardant applications that require transparency and high physical properties.
Advantage
◎Special phosphate ester structure can achieve high flame retardant effect.
◎As it is a glassy flame retardant, can achieve transparent flame retardant effect corresponding to some
types of resins.
◎Has high thermal and hydrolytic stability.
◎Easy to process, minimal migration.
