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)
Sinolstab® UV-3853 is suitable for most polymers including PP (injection molding, film, tape), TPO, and PE (film, tape, injection molding). It can also be used in polyacetals, polyamides, styrenic polymers, and PUR. Typical dosage is 0.1–3.0% depending on the application; appropriate testing should be conducted to determine the optimal level.
