Oceanchem Group APP 205

APP‐205 is a non‐halogenated flame retardant based on APP‐201 which develops its effectiveness through phosphorus / nitrogen synergism. When incorporated into thermoplastics, it exhibits high processing stability. APP‐205 differs in its mode of action from chlorineor bromine‐containing flame retardants by achieving its effect through intumescence. The thermoplastic material foams on exposure to flame. The carbon foam layer so formed protects the polymer through its heat‐insulating effect, reduces fur‐ther oxygen access and prevents dripping of the thermoplastic. APP‐205 may be used in poly‐propylene, PP‐copolymers and PP‐blends.
