UV Absorber UV-1

Product Overview

UV Absorber UV-1 represents an advanced formamidine-type high-efficiency ultraviolet absorber engineered for superior polymer protection. In the demanding landscape of industrial materials, exposure to ultraviolet radiation often leads to significant degradation, resulting in discoloration and loss of mechanical integrity. This specialized chemical additive is designed to mitigate these effects by absorbing harmful UV radiation within the critical 240 to 350 nanometer range. With a maximum absorption peak at 308 nanometers, it provides targeted protection where polyurethane and similar polymers are most susceptible to photocatalytic degradation. Manufacturers seeking to enhance product longevity rely on such stabilizers to maintain aesthetic appeal and structural performance over time.

Technical Specifications

Quality consistency is paramount for industrial manufacturing processes. Our production ensures high purity and strict adherence to performance metrics. The following table outlines the key technical parameters guaranteed for every batch:

Industrial Applications

This ultraviolet absorber is particularly effective in two-component polyurethane coatings and various polyurethane foam systems. It is extensively used in flexible polyurethane foams, thermoplastic elastomers, and microcellular foams. Additionally, it serves integral skin foams, traditional rigid foams, semi-rigid foams, and soft foams. Beyond polyurethanes, it enhances the light stability of fabric coatings, specific adhesives, sealants, and elastomers. It is also compatible with polyvinyl chloride, vinyl polymers, and acrylic resins, offering versatile protection across multiple polymer matrices. The ability to integrate seamlessly into complex formulations makes it a preferred choice for producers of automotive components, construction materials, and consumer goods where weatherability is a key selling point. Its efficacy in microcellular and integral skin foams ensures that even dense polymer structures remain protected from surface degradation.

Performance Benefits

• Effectively prevents yellowing of high-molecular polymers during exposure to sunlight.
• Almost completely absorbs ultraviolet light in the 300 to 330 nanometer region.
• Enhances color stability and prolongs the service life of end products.
• Inhibits photocatalytic degradation effectively in sensitive polymer structures.
• Compatible with a wide range of industrial resin systems and coating formulations.

Storage and Handling

UV Absorber UV-1 is classified as non-dangerous goods, facilitating easier logistics and transportation. The product exhibits good storage stability under recommended conditions. To maintain optimal quality, avoid exposure to high temperatures and humidity during storage and transit. It should be stored in a cool, dry, and ventilated environment to prevent moisture absorption and heat accumulation. Standard packaging involves cardboard drums lined with plastic bags, with a net weight of 25 kilograms per unit, ensuring safe delivery to global manufacturing facilities.
