Excellent color stability, gloss retention, and long‑term durability in polyolefin substrates
Superior compatibility and solubility in polyolefins compared to small‑molecule HALS – significantly reduces exudation and blooming
Good synergistic effects with other high‑molecular‑weight HALS (e.g., Sinolstab® UV-944, UV-119) and with benzotriazole UV absorbers (e.g., Sinosorb® UV 328)
