UV Absorber UV-327

Product Overview

UV Absorber UV-327 represents a premium class of benzotriazole-based ultraviolet stabilizers engineered for extensive polymer protection. As a critical additive in the plastics, coatings, and synthetic fiber industries, this compound effectively absorbs harmful UV radiation, preventing photodegradation and significantly extending the service life of various materials. Our manufacturing process adheres to strict quality control standards, ensuring high purity levels that make it a reliable choice for demanding industrial applications where material integrity is paramount.

Engineered for exceptional stability, this UV absorber exhibits excellent thermal resistance and low volatility, ensuring it remains effective throughout the high-temperature processing and entire lifecycle of the end product. It is particularly valued for its ability to maintain the aesthetic quality of polymers by minimizing yellowing and color shifts caused by prolonged sun exposure. This makes it an indispensable component for manufacturers seeking to enhance the durability and visual appeal of their products.

Technical Specifications

Industrial Applications

This versatile stabilizer is compatible with a wide range of synthetic resins and polymers. It is extensively utilized in the production of polyolefins, engineering plastics, and synthetic fibers. Common applications include protection for polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS), polycarbonate (PC), and polyurethane (PU) systems. Its effectiveness spans across multiple sectors including automotive components, construction materials, and consumer goods.

Beyond standard plastics, UV Absorber UV-327 is suitable for use in ABS, plexiglass, and ethylene vinyl acetate copolymers. Its low mobility ensures that it does not migrate to the surface easily, providing long-term stabilization without affecting the surface properties of the finished goods. This characteristic is crucial for maintaining the mechanical strength and surface finish of outdoor equipment and packaging materials.

Key Advantages

• Superior UV absorption capacity for enhanced weatherability and longevity.
• Excellent thermal stability during high-temperature extrusion and molding.
• Low volatility reduces loss during manufacturing and processing.
• Good compatibility with various polymer matrices ensures uniform dispersion.
• Helps retain mechanical properties and prevents cracking or brittleness.
• Light color profile minimizes impact on final product aesthetics.

Quality Assurance and Storage

Each batch undergoes rigorous testing to verify compliance with specified purity and performance metrics. We provide comprehensive documentation including Certificates of Analysis (COA) to ensure transparency and trust. The product should be stored in a cool, dry, and well-ventilated area away from direct sunlight and heat sources. Keep the container tightly closed when not in use. As a stable chemical, it offers good storage stability under recommended conditions. Standard industrial safety precautions should be followed during handling and transport to ensure workplace safety.
