4. Pigment Orange 64 (Permanent Orange GP) is a bright reddish light orange powder. It has excellent light fastness, heat resistance, solvent resistance, acid resistance, and alkali resistance. In plastics, it can withstand 300°C/5min in HDPE, though the hue shifts toward yellow with increasing temperature, without affecting the crystallinity of the polymer or causing dimensional deformation; it exhibits good migration resistance in plasticized PVC.
