SABOSTAB® UV 91

SABOSTAB® UV 91 by Sabo is a hindered amine light stabilizer blend. It has synergistic performance with high molecular weight HALS, benzoate light stabilizers and UV absorbers. This additive imparts superior solubility and compatibility with polyolefins, for fewer problems relating to exudation (blooming) than other low molecular weight HALS. SSABOSTAB® 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 is used in PP and PE film, tape, and injection molding applications and TPO. Also, used in polyacetals, polyamides, styrenic polymers (ABS, ASA) and polyurethanes. Its applications include PP and TPO automotive parts, TPO roofing membranes, PE crates, and PP outdoor furniture. Recommended dosage for this product 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.
