FR-41B is a highly loaded halogenated masterbatch in a LDPE carrier utilized to improve flame retardancy in olefins and passes several flammability requirements. 10% to 25% addition rates have been shown in testing to be most effective, but individual process will vary.
FR-41NH is a non-halogenated, bromine free flame retardant for olefins which is RoHS/Reach compliant. This masterbatch passes several flammability requirements with a typical blend rate of 15% to 30%.
