Exolit™ OP 1322
Exolit OP 1322 is a non-halogenated flame retardant based on organic phosphinates. The product achieves its flame retardant effect through intumescence and gas phase activity. The thermoplastic polymer with Exolit OP 1322 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 1322 is a white powder.
