Description

1-Hexadecyl 2,3,4-Tris(2,2,6,6-Tetramethyl-4-Piperidyl) Butane-1,2,3,4-Tetracarboxylate is a high-performance hindered amine light stabilizer (HALS) and antioxidant, recognized for its exceptional ability to protect polymers from degradation caused by UV radiation and thermal oxidation. This multifunctional additive is critical for extending the service life and maintaining the mechanical properties of polymeric materials in demanding environments. It is an essential component for formulators and manufacturers in the plastics, coatings, and synthetic fiber industries seeking to enhance product durability.

Application

This advanced HALS compound is designed for high-performance stabilization across multiple polymer systems. Its primary applications include:

• Polyolefin Stabilization: Providing long-term thermal and UV stability to polypropylene (PP) and polyethylene (PE) films, fibers, and molded articles.
• Engineering Plastics: Enhancing the weatherability and color retention of polyamides (PA), polycarbonate (PC), and other engineering resins used in automotive and outdoor applications.
• Protective Coatings: Formulating high-durability industrial, automotive, and architectural coatings to prevent gloss loss, chalking, and cracking.
• Adhesives and Sealants: Improving the longevity and performance of polymer-based adhesives and sealants exposed to sunlight and heat.
• Synthetic Fibers: Stabilizing polypropylene and polyamide fibers against photodegradation, maintaining strength and color in textiles and geotextiles.
• Masterbatch Production: Serving as a key active ingredient in concentrate form for easy dispersion and compounding.
