UV Absorber 4611

Product Overview

UV Absorber 4611 represents a advanced class of compounded high-efficiency light stabilizers engineered to protect polymer matrices from photodegradation. In the demanding landscape of modern materials science, maintaining the structural integrity and aesthetic quality of plastics under prolonged exposure to ultraviolet radiation is critical. This product functions by absorbing harmful UV rays and dissipating the energy as harmless heat, thereby preventing chain scission and cross-linking within the polymer backbone. Our manufacturing process ensures consistent purity and performance, making it an ideal choice for manufacturers seeking long-term durability in outdoor applications.

Key Features and Benefits

The formulation of UV Absorber 4611 is optimized to deliver exceptional performance across a wide range of processing conditions. Unlike standard stabilizers, this compound offers a balanced profile of thermal stability and UV protection. The key advantages include efficient UV resistance that significantly extends the service life of finished products. It exhibits low color pollution, ensuring that the final article maintains its desired hue without yellowing over time. Furthermore, the low volatility characteristic prevents loss of the stabilizer during high-temperature processing or during the product's lifecycle. The material also demonstrates remarkable extraction resistance, ensuring stability even when exposed to solvents or moisture. Users will observe no frost or fog on the surface of the material, guaranteeing excellent optical clarity and surface finish.

Technical Specifications

Industrial Applications

This versatile stabilizer is compatible with a broad spectrum of polymeric systems. It is particularly effective in polyolefin applications such as Polyethylene (PE) and Polypropylene (PP), where weatherability is a primary concern. It is also highly recommended for Polyolefin Thermoplastic Elastomers (TPO) and various Thermoplastic Elastomers including TPE, TPR, SBS, SEBS, SIS, SEPS, TPV, TPU, TPVC, TPEE, and TPA. Additionally, it performs well in Nylon PA formulations. Common end-use sectors include automotive exteriors, construction materials, agricultural films, and outdoor consumer goods where resistance to environmental aging is paramount.

Storage and Handling

To maintain optimal quality, store the product in a cool, dry, and well-ventilated facility. Keep containers tightly closed when not in use to prevent moisture absorption. The material should be kept away from direct light, fire, and heat sources. Safety protocols dictate keeping this chemical away from strong oxidants and strong reducing agents to prevent unintended reactions. Adherence to these storage conditions ensures the product retains its specified physical and chemical properties throughout its shelf life.
