Polysynthren Yellow NG
Polysynthren Yellow NG is a mid-shade yellow for polyester and other selected amorphous engineering polymers. It displays excellent heat stability, sublimation resistance and light fastness. Recommended for all polyester fiber types and for the coloration of PET bottles. The solubility of Polysynthren Yellow NG in styrenic polymers and in PMMA is dependant upon concentration and processing temperature. At a concentration of 0,2% Polysynthren Yellow NG is soluble above 250°C. Light fastness at this concentration is 7-8 blue wool scale.
