UV Absorber UV-360

Product Overview

UV Absorber UV-360 is a specialized high molecular weight ultraviolet stabilizer engineered for demanding polymer applications. Operating effectively within the 300 to 400 nanometer range, this compound provides superior light stabilization by converting harmful ultraviolet radiation into harmless heat energy through photochemical actions. Its robust chemical structure ensures exceptional thermal stability, making it an ideal choice for processing environments that require low volatile content and high weather resistance. Manufacturers seeking reliable protection against photodegradation will find this product essential for maintaining the integrity and aesthetic quality of finished plastic goods. Unlike lower molecular weight alternatives, this grade offers sustained protection over the lifecycle of the product.

Designed for versatility, this absorber exhibits minimal migration tendencies due to its high molecular weight. This characteristic effectively prevents precipitation on molds and die lips during extensive manufacturing cycles. The material maintains clarity and performance even under rigorous processing conditions, ensuring that the final products meet stringent industry standards for durability and appearance.

Technical Specifications

Our quality control ensures every batch meets rigorous purity and performance metrics. The following table outlines the key physical and chemical properties associated with this grade.

Industrial Applications

This UV absorber is particularly suitable for high processing temperature polymers such as polycarbonate systems. Its compatibility extends across a wide range of engineering plastics including acrylic resins, PET, modified polyphenylene ether, sulfide compounds, polyamides, polyolefins, styrenes, and elastomers. The low volatility profile allows it to perform consistently in high-temperature environments without significant loss due to evaporation or sublimation. In automotive components and outdoor construction materials, where long-term exposure to sunlight is inevitable, this stabilizer plays a critical role in preventing cracking, yellowing, and loss of mechanical strength.

Furthermore, it is applicable in casting, thin-layer construction of fibers, paper, wallpaper, and adhesives. The ability to be processed via powder, solution, or melt extrusion molding provides flexibility for various manufacturing setups. Users can combine this product with other light stabilizers or antioxidants to create synergistic effects that enhance overall material lifespan and reduce warranty claims related to weathering failures.
