UV-366: A Balanced UV Absorber for Plastic & Textile Protection

In the field of protective raw materials for polymer materials and textile products, the absorption efficiency, stability, and adaptability of UV absorbers are central concerns in R&D. As a novel benzotriazole-based UV absorber, UV-366 offers a reliable option for enhancing the protection of related products due to its inherent properties.

In terms of absorption performance, UV-366 demonstrates strong UV-absorbing capabilities. Compared to traditional hydroxy-substituted benzotriazole or benzophenone UV absorbers, it exhibits higher UV absorption rates. This property helps reduce polymer photodegradation, providing targeted protection for materials. Its UV molar extinction coefficient is notably high—2.6 times that of benzophenone-based UV absorbers and 1.8 times that of traditional benzotriazole (alkylphenol-substituted derivative) UV absorbers—providing data-backed support for high-efficiency protection.

Regarding product stability and processing compatibility, UV-366 offers multiple practical advantages. Its high molecular weight makes it less volatile and more resistant to extraction compared to some traditional UV absorbers, ensuring relative stability during processing and use. Its pale yellow appearance prevents polymer discoloration or staining during use. Even after prolonged exposure to light and heat, it helps maintain the original transparency or color of the product, making it suitable for product development with high aesthetic requirements.

UV-366 demonstrates flexible adaptability in application methods. It can be used alone or in combination with light stabilizers (such as hindered amine compounds). It can be directly blended with resins, pre-formulated into masterbatches, or dissolved in solvents for surface coating on products, offering diverse options for different production processes. Its recommended dosage is 0.25-0.3%, offering moderate and easily controllable usage that simplifies formulation adjustments.

UV-366 exhibits broad applicability. In plastics, it works with general-purpose materials like PP and PE, as well as polystyrene, ABS resin, PVC, nylon, polyurethane, and more. In textiles, it effectively inhibits photo-oxidative degradation in fiber materials with strong adsorption properties—particularly outperforming triazine UV absorbers on microfibers—and demonstrates excellent compatibility with polyester fibers, enhancing protective qualities in textile products.

UV-366 establishes its competitive edge through balanced performance in UV absorption efficiency, stability, processing flexibility, and broad applicability. It not only meets the fundamental protection requirements for polymer materials and textile products but also supports product quality upgrades. For enterprises engaged in plastic processing, textile production, and related raw material R&D with UV protection needs, UV-366 is a practical raw material choice worthy of attention.

We invite industry partners to explore UV-366's specific characteristics, adapt formulations to their product development needs, leverage its performance advantages to optimize protective effects, and jointly create high-quality products that meet market demands.
