Light Stabilizer 119

Product Overview

Light Stabilizer 119, also known commercially as Chimassorb 944, represents a class of high molecular weight hindered amine light stabilizers (HALS). This advanced chemical additive is engineered to provide exceptional longevity and durability to polymers exposed to harsh environmental conditions. By effectively scavenging free radicals generated during UV exposure, it significantly slows down the photodegradation process, preserving the mechanical integrity and aesthetic appearance of plastic materials.

Our manufacturing process ensures high purity levels, making this stabilizer an ideal choice for demanding applications where performance consistency is critical. Unlike low molecular weight alternatives, this polymeric HALS offers reduced volatility and minimal migration, ensuring long-term protection throughout the lifecycle of the finished product.

Technical Specifications

Industrial Applications

This stabilizer is versatile and compatible with a broad spectrum of polymer matrices. It is particularly effective in polyolefins such as polyethylene (PE) and polypropylene (PP), including talc-filled compounds used in automotive industries. The product is extensively utilized in the production of agricultural films, where resistance to agrochemicals is essential. Additionally, it performs excellently in styrenic polymers like ABS and ASA, polyamide fibers, polyurethanes, and various elastomers.

In the coatings sector, Light Stabilizer 119 contributes to the triboelectric effect in powder coatings while maintaining robust light stability. Its compatibility with other stabilizers allows for synergistic formulations, enhancing overall performance when used alongside UV absorbers or benzoates.
