Bisoctrizole (UV Absorber 360)

Product Overview

Bisoctrizole, commercially known as UV Absorber 360, is a premium high-efficiency ultraviolet absorber engineered for the stabilization of various polymeric materials. This advanced chemical compound functions by effectively absorbing harmful UV radiation in the 300 to 400 nanometer range, thereby preventing photo-oxidative degradation that can lead to discoloration, cracking, and loss of mechanical integrity in finished products. As a benzotriazole derivative, it offers exceptional compatibility with a broad spectrum of resins, making it a versatile choice for demanding industrial applications.

Our manufacturing process ensures high purity levels, typically exceeding 99 percent assay, which guarantees consistent performance across batches. The product is characterized by its light yellow powder appearance and possesses significant thermal stability, allowing it to withstand high-temperature processing environments without decomposing or losing efficacy. This makes it particularly suitable for polymers that undergo rigorous extrusion or molding processes.

Key Specifications

Industrial Applications

UV Absorber 360 is extensively utilized in the stabilization of engineering plastics and high-performance resins. Its low volatility profile ensures that it remains within the polymer matrix during processing and throughout the product's lifecycle, providing long-term protection against weathering and UV exposure. Key application areas include:

• Polypropylene (PP) and Polyolefin systems requiring enhanced durability.
• Polycarbonate (PC) and Polyimide materials used in automotive and electronic components.
• Polyamide and Polyacetal resins where mechanical strength retention is critical.
• Modified polyphenylene ether and polystyrene formulations.
• Elastomers and fiber constructions needing thin-layer UV protection.

The additive can be processed via extrusion in powder, solution, or melt forms, which helps prevent crystallization issues during manufacturing. Furthermore, it exhibits minimal exudation and sublimation, making it ideal for casting processes and thin-layer constructions such as fiber, paper, and wallpaper coatings. It can also be used synergistically with other light stabilizers or antioxidants to create a comprehensive stabilization package.

Storage and Handling

This ultraviolet absorbing agent is classified as non-toxic, non-flammable, and non-explosive, facilitating safe handling and transport. It is not considered dangerous goods under standard shipping regulations. For optimal storage stability, the product should be kept in a cool, dry, and well-ventilated area, away from direct sunlight and moisture. When stored under recommended conditions in its original packaging, typically 25kg cardboard drums lined with plastic bags, the material maintains its specified properties over extended periods. We provide full Certificates of Analysis (COA) with every shipment to ensure compliance with quality standards.
