Technological watch

The present disclosure relates to a novel flame retardant and colorant additive composition for thermoplastic polymers, the additive composition including at least one phosphorus- containing flame retardant and an orange colorant, as described herein. The presently disclosed additive compositions are useful over a wide range of thermoplastic applications, particularly in thermoplastic polymers that are processed and/or used at high temperatures. The resultant thermoplastic compositions have a οE of <20, preferably a οE<10, more preferably οE<5, from a color number beginning with "2" in the RAL color chart. Use of the additive composition improves processing of thermoplastics.
