Light Stabilizer 5050H

Product Overview

Light Stabilizer 5050H is a high-performance, oligomeric hindered amine light stabilizer (HALS) engineered for demanding polymer applications. With a molecular weight range of 3000–4000 g/mol, it delivers exceptional compatibility in polyolefin matrices—particularly polyethylene (PE) and polypropylene (PP)—while minimizing water carry-over during processing. This advanced additive is widely recognized under trade names such as Uvinul 5050 H and functions as a robust solution for long-term photostabilization in both thin and thick-section plastic articles.

Specifications and Physical Characteristics

Industrial Applications

Light Stabilizer 5050H is specifically formulated for use in a broad spectrum of polymer systems requiring durable resistance to UV degradation and thermal aging. Key applications include:

• PP and PE tapes with reduced moisture uptake
• PP fibers and nonwovens
• PE agricultural and packaging films
• Thick-section molded parts in PP and PE
• Olefin copolymers such as EVA
• PP/elastomer blends
• Flexible and rigid PVC formulations

Recommended dosage levels vary by application: 0.1–1.4% for fibers, 0.1–0.8% for tapes, 0.05–1.0% for thick sections, and 0.1–1.0% for films. Its oligomeric structure ensures low volatility, excellent extraction resistance, and minimal migration—critical for maintaining product integrity over extended service life.

Handling and Packaging

Supplied in 20 kg cartons, Light Stabilizer 5050H should be stored in a tightly closed container in a cool, dry environment to preserve stability and performance.
