Description

Chimassorb 119 is a high-performance, polymeric hindered amine light stabilizer (HALS) designed for long-term protection of polymers against photo-oxidative degradation. This compound is critical for extending the service life and maintaining the mechanical properties and color of plastics exposed to ultraviolet (UV) light. It is an essential additive for manufacturers in the plastics, coatings, and synthetic fiber industries who require reliable UV stabilization for their products.

Application

• Polyolefin Stabilization: Primary use in protecting polypropylene (PP) and polyethylene (PE) films, fibers, and molded articles from UV-induced embrittlement and color change.
• Automotive Plastics: Used in interior and exterior automotive components, such as bumpers, dashboards, and trims, to prevent fading and cracking from sunlight exposure.
• Agricultural Films: Critical for greenhouse films and mulch films to ensure durability and maintain light transmission properties throughout the growing season.
• Industrial Coatings: Incorporated into protective coatings for outdoor structures, industrial equipment, and marine applications to enhance weatherability.
• Synthetic Fibers: Stabilizes polyolefin-based fibers used in outdoor textiles, geotextiles, and artificial turf against UV degradation.
• Engineering Plastics: Provides light stabilization for various engineering plastics used in construction materials and outdoor appliances.

Quality Control

Our Chimassorb 119 is manufactured under a strict quality management system to ensure batch-to-batch consistency and high performance. The product undergoes rigorous testing, including analysis of active content and thermal stability, to meet the demanding requirements of the polymer industry. Certificates of Analysis (COA) documenting key specifications are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed when not in use to prevent moisture absorption, which can affect performance.
