Exolit® OP 1312 is a non-halogenated flame retardant based on organic phosphinates. The product achieves its flame retardant effect through intumescence. The thermoplastic polymer with Exolit® OP 1312 foams and crosslinks on exposure to flame and forms a stable char at the surface acting as a barrier. The protective layer provides a heat insulating effect, reduces oxygen access and prevents dripping of molten polymer. Exolit® OP 1312 is a white powder.
