SABO® STAB UV 91

Technical DataSheet | Supplied by Sabo

SABO® STAB UV 91 by Sabo is a mixture of 2,2,6,6-tetramethylpiperidin-4-yl-hexadecanoate and 2,2,6,6-tetramethylpiperidin-4-yl-octadecanoate. Acts as a light stabilizer blend. It has synergistic performance with high molecular weight HALS, benzoate light stabilizers and UV absorbers. Imparts superior solubility and compatibility with polyolefins, for fewer problems relating to exudation (“blooming”) than other low molecular weight HALS. SABO® STAB UV 91 outperforms other HALS in polyolefin substrates in terms of color stability, gloss retention and property retention. Its concentrate form provides easy handling and dosing in polymer processing operations. It can also be used for the light stabilization of PP and PE film, tape, TPO, polyacetals, polyamides, styrenic polymers (ABS, ASA) and polyurethanes. Its applications include PP and TPO automotive parts, TPO roofing membranes, PE crates, PP outdoor furniture and adhesives. Recommended dosage for SABO® STAB UV 91 is 0.05 to 1.5%, depending upon the application. It is listed on the ECL, ELINCS, ENCS, IECSC, PICCS, NZIoC, TCSI, AICS, DSL and TSCA chemical inventories. It has a shelf life of 5 years.
