Light Stabilizer 3853PP5

Product Overview

Light Stabilizer 3853PP5 is a high-performance, 50% active concentrate of a hindered amine light stabilizer (HALS) dispersed in a polypropylene carrier resin. Designed specifically for polyolefin-based formulations, it delivers exceptional resistance to UV-induced degradation, ensuring long-term color stability, gloss retention, and mechanical integrity in outdoor and automotive applications.

Specifications and Physical Characteristics

Industrial Applications

This specialty additive is ideally suited for polypropylene (PP) film, tape, injection molding, and thermoplastic olefin (TPO) systems. Key end-use markets include automotive exterior and interior components, TPO roofing membranes, and outdoor furniture—applications where prolonged exposure to sunlight demands robust photostabilization.

Light Stabilizer 3853PP5 exhibits strong synergistic effects when combined with high molecular weight HALS (e.g., LS 944, LS 119), benzoate-type stabilizers (e.g., UV 328), and other UV absorbers, enabling formulators to optimize performance while reducing overall additive load.

Key Advantages

• Outperforms conventional low molecular weight HALS in color and gloss retention within polyolefin matrices
• Superior solubility and compatibility with PP and TPO, minimizing exudation (“blooming”)
• Low volatility and excellent resistance to migration during processing and service life
• Convenient granular concentrate form ensures accurate dosing and homogeneous dispersion
• Complies with multiple global food contact regulations, expanding applicability in regulated packaging

For safe handling, store in a tightly closed container in a cool, dry environment. Always refer to the Material Safety Data Sheet (MSDS) for comprehensive safety and regulatory guidance.
