Exolit™ OP 1242 by Clariant is a non-halogenated flame retardant based on organic phosphinates. It achieves its flame-retardant effect through a combined gas phase and condensed phase mode of action. The thermoplastic polymer with it forms on exposure to flame a stable char at the surface acting as a barrier. It provides a heat-insulating effect, reduces oxygen access, and prevents dripping of molten polymer. <br>
