Explanation

Yes, it is correct. Tetrabromophthalic anhydride is a reactive flame retardant incorporated into unsaturated resins. Isoindoline is used as colorant in PVC and polypropylene and some engineering plastics. 2-hydroxybenzotriazole is used as UV stabiliser for polymers. Dioctylphthalate is used as PVC Plasticiser.
